11 Chapter 1 Overview Introduction Ascent Xtrata delivers a trio of components that extend Ascent Capture s document and data capture capabilities. Xtrata provides enhanced form identification (classification), document separation, unsurpassed image registration, and assisted form set up. Once Ascent Xtrata is installed, you can add Xtrata Server to your batch classes. With the settings that are enabled by default, Xtrata Server performs classification and registration of form types defined through normal Ascent Capture methods. If desired, you can enable advanced Xtrata options that facilitate form type set up. The Xtrata Forms Setup interface in the Ascent Capture Administration module allows you to easily set up form types and zones. You can provide sample images and initiate zone set up directly in Xtrata Forms Setup, or take advantage of Xtrata s ability to learn forms and zone locations with definition batches. Xtrata allows you to scan new forms as definition batches that are processed differently from production batches. Definition batches use a special-purpose batch class installed with Ascent Xtrata. Batches created with this batch class are processed through Xtrata Server, where similar images in the batch are automatically clustered into sample pages. As soon as at least five images exist in a cluster, Xtrata Server locates all fields (boxes, combs, check boxes, and lines) on the page. The results of this processing are made available to Xtrata Forms Setup, where it can be used to quickly set up form types and zones. This chapter introduces the components installed with Ascent Xtrata and the key features provided with the product. The rest of this guide describes the components in more detail, and explains how to incorporate Xtrata functionality into your Ascent Capture processing flow. Getting Started with Ascent Xtrata 1

12 Chapter 1 Custom Components Features The following custom components are provided with Ascent Xtrata: Xtrata Server is a custom module that you can add to your Ascent Capture batch classes to perform Xtrata processing. It runs as an unattended module to perform form type classification, document separation and enhanced image registration, as well as automatic rotation of images that were scanned upside down, black border removal, and Optical Mark Recognition (OMR). Xtrata Server can also process definition batches, for which it clusters similar images as new sample pages, identifies zone locations, and stores the definition information for use with Xtrata Forms Setup. Xtrata Forms Setup is a custom panel added to the Ascent Capture Administration module. It provides assisted form type and zone set up from an easy-to-use interface. For example, Xtrata Forms Setup allows you to create form types and sample pages from sample images that you provide or images available from processing definition batches with Xtrata Server. You can also create and edit zones right in Xtrata Forms Setup, and/or accept zones found by Xtrata. Xtrata Form Type Correction is a custom panel added to the Ascent Capture Quality Control module. It allows you to easily assign form types to unclassified images, or remove images of new form types from the batch. Images that you remove can be made available for definition batch processing, where Xtrata Server can learn the form types and identify the zone locations. The following sections highlight many of the benefits provided with Ascent Xtrata. Easy Installation Ascent Xtrata is easy to install on any Ascent Capture client or standalone station. Just insert the Ascent Xtrata installation CD and follow the instructions presented to you. In addition, the installation process automatically registers the custom Xtrata components with Ascent Capture. Integrated with Ascent Capture Xtrata Server is installed and registered as an Ascent Capture custom module that you can add to your Ascent Capture batch classes just like any other Ascent Capture 2 Getting Started with Ascent Xtrata

13 Overview module. When batches based on the batch classes are processed, they are automatically routed through Xtrata Server as part of the defined Ascent Capture workflow. Other Xtrata custom components are easily accessible from the Ascent Capture Administration and Quality Control modules. Enhanced Form Type Classification Ascent Xtrata provides enhanced form identification functionality, being able to classify up to 1,000 different form types in one batch class with high speed and accuracy. Document Separation and Consistency Check Ascent Xtrata performs document separation based on classification results. The first page of a document is detected by matching a loose page with all first sample pages defined for the batch class. Additional loose pages are added to the document if they match a second page or do not match any first page. If the batch contains already separated documents, these will be used for classification. In addition to creating documents, Xtrata Server can perform a check on document length and page sequence within the document. The page sequence is determined by the sample pages defined for the form type that is assigned to the document. If an error in sequence is detected, Xtrata Server can either raise an error that leads to manual correction in the Ascent Capture Quality Control module or try to resort the document automatically by matching all pages of the document with all sample pages of the assigned form type. Advanced Registration Xtrata registers images without the need to define registration zones or anchors. Registration is done in relation to the stored sample images that were used to draw index zones during batch class set up. For multipage documents, registration and optionally background removal is performed for each page that corresponds to a sample page with index zones. For classification and registration, it does not matter if the index zones are created via Xtrata Forms Setup and segmentation or manually in the Ascent Capture Administration module. Getting Started with Ascent Xtrata 3

14 Chapter 1 In addition, Xtrata s registration automatically adjusts for stretched or scaled images to match the index zones to the images. This can greatly decrease data capture errors caused by incorrectly registered images, and reduce the amount of manual indexing. Assisted Form Type Setup For Xtrata batch classes, the Xtrata Forms Setup interface is available in the Ascent Capture Administration module to assist in form type set up and index zone definition. It can be used in conjunction with normal Ascent Capture methods for defining form types and zones during batch class definition. Segmentation Ascent Xtrata can perform internal segmentation of images, whereby it analyzes the images and identifies form fields (boxes, combs, check boxes, and lines) that are candidates for zones. The segmentation data is made available to Xtrata Forms Setup for easy zone definition. Enhanced Zone Manipulation Xtrata Forms Setup allows you to accept and manipulate all zones found during segmentation, or individual zones as desired. It also allows you to lasso an area of interest on an image and accept all zones within the area. Accepting zones is as easy as pointing your mouse and clicking on the zones. In addition, Xtrata Forms Setup allows you to edit one or more zones at the same time. For example, you can select multiple zones in the Xtrata Forms Setup viewer and resize, move, and/or edit the properties of all of them at once. Ability to Learn Forms Ascent Xtrata allows you to scan or import definition batches that automatically prepare images and segmentation data for easy forms set up. Definition batches use a special-purpose definition batch class that is installed with Ascent Xtrata. For definition batches, Xtrata Server clusters the images into sample pages for classification and performs segmentation of zones on the images. Then, it makes the images and segmentation data available to Xtrata Forms Setup in the Ascent Capture Administration module. Xtrata Forms Setup can then be used to add the sample pages to a document class and set up zones. In addition, Ascent Xtrata allows you to save the images used in definition batches, and process them in production batches without the need to rescan. 4 Getting Started with Ascent Xtrata

15 Overview Automatic Rotation With Ascent Xtrata, presorting batches to ensure proper orientation of the documents is no longer necessary. Xtrata Server can detect images scanned upside down, and automatically rotate them by 180 degrees. Background Removal Ascent Xtrata provides the ability to work with forms for which background items (such as lines or combs within zones) are removed temporarily for character recognition. This can improve recognition results by allowing zone data to be processed without field structures. Xtrata s ability to perform background removal eliminates the need to redesign your forms and print them using dropout ink. Assisted Form Type Correction For unclassified images, the Xtrata Form Type Correction interface is available in the Ascent Capture Quality Control module. This easy-to-use interface displays the available form types side-by-side with the first page of unclassified documents to help you choose the appropriate form type. This interface sorts the list of available form types by confidence value. The form types with the highest confidence for a match are listed first. This makes it easy to assign the correct form type without having to check all form types in the list. In addition, Xtrata Form Type Correction allows you to easily remove unclassified images from a batch, and store the images where they can be used in definition batches.

29 Chapter 3 Setting Up Batch Classes with Ascent Xtrata Introduction Once Ascent Xtrata is installed, you can add Xtrata Server to your batch classes. With the settings that are enabled by default, Xtrata Server performs classification and registration of form types defined through normal Ascent Capture methods. You can use additional functionality from Xtrata Forms Setup to facilitate form type set up. This chapter describes how to set up batch classes with Xtrata Server, and concentrates on the basic functionality of Ascent Xtrata. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for information about the features of Xtrata Forms Setup. Getting Started with Ascent Xtrata 19

30 Chapter 3 Functionality Overview At runtime, Xtrata Server provides classification and enhanced registration of Ascent Capture form types and index zones that have been defined for a batch class. Batches processed through Xtrata Server are typically sent to Recognition Server for further processing, such as automatic data capture and recognition. Unclassified images will cause the batch to be routed to the Quality Control module, where the images can be manually classified using the Xtrata Form Type Correction custom panel. Xtrata Server registers classified images without the need to define registration zones or anchors. Registration is done in relation to the stored sample pages that were used to draw index zones during batch class set up. Ascent Xtrata registration corrects small shifts, skew, and linear stretching to match the index zones on the image. Xtrata Forms Setup provides additional functionality for Xtrata Server, and facilitates setting up form types and defining zones from the Administration module. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for further information. Typical Runtime Workflow Figure 3-1 illustrates a typical Ascent Capture workflow that includes Xtrata Server. Figure 3-1. Typical Workflow with Xtrata Server 20 Getting Started with Ascent Xtrata

31 Setting Up Batch Classes with Ascent Xtrata In the example workflow, batches are scanned or imported into Ascent Capture, and then sent to Xtrata Server where Xtrata runtime processing occurs. In addition to classification and registration, Xtrata Server can automatically rotate images that were scanned upside down and/or remove black borders. Additionally, you can select settings to consider a fixed page length for a document and to ignore classification and/or fixed page length errors. To classify images, Xtrata Server uses internal templates and patterns created from the sample pages defined for the form types in the batch class. At runtime, Xtrata Server compares the images in the batch to the internal patterns. If a match within a specified confidence threshold is found, Xtrata Server assigns the form type to the image. If the confidence is lower than the threshold, Xtrata Server leaves the image unclassified. In this case, the image can be identified by processing it through Recognition Server (if form identification is defined for the batch class). Alternatively, the image can be manually identified in the Quality Control module. Ascent Xtrata installs a special-purpose panel to the Ascent Capture Quality Control module that facilitates the manual classification process. (See Chapter 6.) Batches that contain unclassified documents or documents with an incorrect number of pages are routed to the Ascent Capture Quality Control module, where the Xtrata Form Type Correction panel can be used to manually classify forms. How Xtrata Server handles documents with errors is specified as an Xtrata batch class property (Runtime tab). Refer to Error Options on page 29 for more information. Then, batches flow through the defined Ascent Capture workflow for processing and release. Batch Class Settings When Xtrata Forms Setup (described in Chapter 4) is not used to create form types, then Xtrata Server uses batch classes set up through standard Ascent Capture methods. You need only add Xtrata Server to the list of queues for the batch class. However, classification can be improved by adding more classification sample images during batch class set up, through a special-purpose Xtrata interface available from the Ascent Capture Administration module. The following sections describe how to add Xtrata Server to your batch classes and use the various Ascent Xtrata batch class settings. Getting Started with Ascent Xtrata 21

32 Chapter 3 Adding Xtrata Server to a Batch Class To process batches through Xtrata Server, you must add Xtrata Server to your list of processing queues for a batch class. You can add Xtrata Server as a processing queue when creating new batch classes or editing existing ones in Ascent Capture. Ascent Xtrata will always use any currently defined batch class, document class, and form type settings for the batch class, even if the settings change after Xtrata Server is added. Refer to Batch Class Considerations on page 31 for more information about the required batch class settings and limitations for batch classes that include Xtrata Server. Once Xtrata Server is added to a batch class, several items are added to context menus for that batch class. Xtrata Settings and Xtrata Forms Setup become available on the context menu for the batch class. Work On Dropped Out Image and Load Original Sample Page become available on the context menu for form types with background removal enabled. (Only one of these items is available on the context menu at a time. If Work On Dropped Out Image is selected, the context menu will show Load Original Sample Page and vice versa.) Add Classification Sample Images becomes available on the context menu for the sample pages. Refer to Xtrata Settings on page 23, Background Removal on page 74 and Additional Sample Images for Classification on page 36 for more information about these items. The procedure below describes how to add Xtrata Server to an existing batch class. Refer to your Ascent Capture documentation for details about creating batch classes. To add Xtrata Server to an existing batch class 1 From the Administration module s Definitions panel, select the Batch class tab. 2 Right-click the batch class to which you want to add Xtrata Server. 3 From the context menu, select Properties. The Batch Class Properties dialog box will display. 4 Select the Queues tab. 5 Select Xtrata Server from the list of Available Queues and click Add. Xtrata Server will move to the list of Selected Queues. It will appear in the list right after the Scan module. If Recognition Server is in the list, Xtrata Server must appear before Recognition Server. 22 Getting Started with Ascent Xtrata

33 Setting Up Batch Classes with Ascent Xtrata Note Xtrata Server is registered as a custom module when you install it. If it is installed but not in the list of Available Queues, you can use the Ascent Capture Custom Module Manager to register Xtrata Server. Refer to Registering Custom Components on page 13 for information on registering Ascent Xtrata components. Xtrata Settings Figure 3-2. Xtrata Server in List of Selected Queues 6 Click Apply to save your settings without closing the Batch Class Properties dialog box. Click OK to save your settings and close the dialog box. Adding Xtrata Server to a batch class adds the Xtrata Settings option to the context menu for the batch class. Selecting the menu item Xtrata Settings opens the Xtrata Settings dialog box, from which you can specify various Ascent Xtrata settings. The settings are batch class specific, meaning that you can set different settings for each batch class that includes Xtrata Server as a processing queue. Getting Started with Ascent Xtrata 23

34 Chapter 3 To open Xtrata Settings 1 From the Administration module s Definitions panel, select the Batch class tab. 2 Right-click a batch class that includes Xtrata Server. The context menu for the batch class will display. Note The Xtrata Settings option (shown below) will only be available in the context menu if the selected batch class includes Xtrata Server as a processing queue. If Xtrata Settings is not an option, verify that you selected the desired batch class, and that the batch class includes Xtrata Server as a processing queue. Refer to Adding Xtrata Server to a Batch Class on page 22. Figure 3-3. Xtrata Settings in Context Menu for a Batch Class 3 From the context menu, select Xtrata Settings. The Xtrata Settings for the Batch Class dialog box will display. The options available from this dialog box are described in the following sections. Runtime Tab Settings on the Runtime tab allow you to specify confidence thresholds for form classification and also various multipage and error handling options. These options specify the thresholds that Xtrata Server will use to classify images, and other functionality performed during Xtrata Server processing. 24 Getting Started with Ascent Xtrata

35 Setting Up Batch Classes with Ascent Xtrata Figure 3-4. Xtrata Settings for Batch Class - Runtime Tab Classification The Classification area provides two sliders that allow you to set the absolute confidence and difference required for confident classification during Xtrata Server processing. Only images that are classified with a confidence above the configured threshold are assigned a form type by Xtrata Server. Images that cannot be classified within the configured threshold remain unclassified by Xtrata Server. In addition, you can select a default form type that Xtrata Server will use for any documents that it cannot confidently classify. Minimum confidence This is the absolute confidence required for classification by Xtrata Server. Valid values are from 0% to 100%. The default value is 70%, which is recommended for high quality and very low error rates for typical forms. Lower values lead to Getting Started with Ascent Xtrata 25

36 Chapter 3 fewer unclassified images, but can increase the error rate. Typical values are from 65% to 70%, depending on the images. Minimum difference This is the minimum difference required between one confidence result and the next best confidence result for classifying an image. If the difference between the returned confidence values is less than the minimum difference, Xtrata Server will not consider the image a match for the form type. Valid values are from 0% to the Minimum confidence. A value of 10% is recommended as a good value to discriminate between similar forms, but can be adjusted depending on the images. A value of 0% means that no difference is required for valid classification. The best confidence will win with no respect to the second best. If the confidences of the first two results are equal, the first match found will be taken. This could result in incorrect classification if the form types are very similar. Default form type The combo box allows you to select one form type as a default form type from the list of all Ascent Capture form types for the batch class. If a default form type is selected, any unclassified document is assigned that form type in Xtrata Server. This means that all documents will be assigned a form type in Xtrata Server, and no documents will be left unclassified. By default, no default form type is selected as a runtime option. Note A default form type is not assigned to documents that have an edocument as the first page. Refer to edocuments in Xtrata Server on page 34 for more information. Settings The Settings area allows you to select various Xtrata Server runtime processing options. Auto rotation 180 degrees If enabled, Xtrata Server performs format-based automatic 180-degree rotation of images, based on classification and pattern recognition. During processing, Xtrata Server will detect that an image is flipped (for example, scanned upside down compared to the sample pages for the form type), and automatically rotate it by 180 degrees. This allows you to scan batches without regard to the orientation of 26 Getting Started with Ascent Xtrata

37 Setting Up Batch Classes with Ascent Xtrata the pages in the batch, thus reducing manual batch preparation time. Auto rotation is enabled by default. Black border removal If enabled, Xtrata Server performs black border removal on the images. When scanning in color, the black borders are cropped from both the color image and the bitonal image used internally by Ascent Capture. Black border removal is disabled by default. If you know that the images in your batches will not have black borders when they are processed by Xtrata Server, you can disable this option to speed up Xtrata Server runtime performance. This might be the case if black border removal is performed at scan time. Note It is recommended that you perform black border removal at scan time using a VRS-enabled scanner. This is the fastest, most secure and highest quality method of getting clean deskewed images. If this is not possible (for example, you are importing images or scanning with a non-vrs-enabled scanner), it is recommended that you perform black border removal in Xtrata Server. While it is possible to configure black border removal with cropping as permanent image clean up in Ascent Capture, you should not use this Ascent Capture feature with Ascent Xtrata. Xtrata Server registers zones based on uncropped images, and the zones will be misaligned if Ascent Capture changes the image size by cropping the image. OMR When enabled, OMR recognition for all index zones set for OMR processing will be performed by Xtrata Server, rather than Ascent Capture Recognition Server. Xtrata Server will use its own built-in OMR reader to find OMR boxes and return the results to Ascent Capture. OMR (for Xtrata Server) is disabled by default. Classification only If enabled, Xtrata Server will perform classification only. It will not perform registration of zones. Enabling this option is recommended if no index zone processing is required or you want to perform registration with the Ascent Capture Recognition Server module. For this case, you can enable Classification only to improve Xtrata Server runtime performance. Classification only is disabled by default. Undefined scanning This option adds the ability to move unclassified images from Xtrata Form Type Correction in Quality Control to Xtrata Forms Setup in the Administration Getting Started with Ascent Xtrata 27

38 Chapter 3 module and make them available for the set up of new form types. Undefined scanning is disabled by default. If you select this option, a new button is added to the toolbar of the Xtrata Form Type Correction panel available in Quality Control. The button allows the operator to remove images representing new sample pages from the batch and store them in the folder for definition images for later use in setting up forms. Refer to Folder for Definition Images on page 30 for more information about. For example, the images in the folder can be processed in an Xtrata definition batch, and the results used in Xtrata Forms Setup to define new form types and set up zones. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for information about Xtrata Forms Setup and definition batches. Refer to Chapter 6 Correcting Classification Results on page 115 for information about Xtrata Form Type Correction. OCR registration Standard Ascent Xtrata registration corrects small shifts, skew, and linear stretching by adjusting the image using graphical elements such as lines, company logos, address labels, or other background items. With OCR registration, the image is aligned to the machine printed text of the document. The advantage of this option is that it can correct for larger shifts, skew, and linear stretching than standard registration, or can be used for documents having only a few graphical elements. The disadvantage is that it requires more computing time, because full text OCR must be performed for all pages. OCR registration is most effective for images with varying layout, and where at least 80-90% of the image text matches the text on the sample pages. In general a scan resolution of 300 dpi is recommended to get good OCR results, but it is not obligatory. To enable OCR registration, select the OCR registration option from the Xtrata Settings for Batch Class dialog box. Multipage Options The Multipage Options area allows you to select a special option for processing fixed length form types. Enforce fixed page length for form type If this option is selected, Xtrata Server will use it in the creation of documents that have been assigned to a form type with a fixed number of pages. The value for the number of fixed pages used for this option is set within the Ascent Capture form type properties. Refer to the Getting Started with Ascent Capture guide for details about setting up fixed length form types. This option is disabled by default. 28 Getting Started with Ascent Xtrata

39 Setting Up Batch Classes with Ascent Xtrata Note You cannot define more sample pages than the number of fixed pages defined for the form type. Otherwise a publishing error occurs. Normally, Xtrata Server creates a new document only when a page is classified as the first page of a document. However, when this option is set and the current document already has the maximum number of pages for the form type, Xtrata Server creates a new document from the next loose page even if that loose page cannot be classified. No form type is assigned to the new document, unless a default form type is selected as a classification option on the Runtime tab. Then, this document is assigned to the default form type. Note For a batch that contains only documents and no loose pages (for example, when you have set the Kofax fixed pages option on the Separation and Form Identification tab for the batch class properties), this option is not taken into account. Error Options The Error Options area provides various Xtrata Server error options. Ignore classification errors If Xtrata Server cannot classify a document, by default the document will be rejected and routed to Quality Control. If this option is checked, Xtrata Server will not reject the document. Instead, it will route the document to Recognition Server with no form type assigned. Recognition Server can then try to classify the document (for example, using form identification zones), and will reject the document if that is not possible. This option is disabled by default. Ignore reordering errors If this option is checked, Xtrata Server will not reject a document when a reordering error occurs. Instead, it will route the document to Recognition Server. Recognition Server will check the document for page length but not for the sequence of pages. Note that Document Reordering is an advanced feature that must be configured within Xtrata Forms Setup. Refer to Xtrata Form Type Properties on page 74 for further information. This option is disabled by default. Ignore fixed page errors If this option is checked, Xtrata Server will not reject the document. Instead, it will route the document to Recognition Server. Recognition Server will check the document and possibly reject it if the number of pages is not correct. This option is disabled by default. Getting Started with Ascent Xtrata 29

40 Chapter 3 Setup Tab Options on the Setup Tab allow you to specify settings that impact setting up form types with Xtrata Forms Setup. Figure 3-5. Xtrata Settings for Batch Class - Setup Tab Folder for Definition Images With Undefined scanning, images representing a new sample page can be removed from a batch in the Xtrata Classification Correction panel available in Ascent Capture Quality Control, and made available to Xtrata Forms Setup in the Administration module. These images are stored in the specified folder, and can then be re-imported as a definition batch to create new unassigned sample pages for Xtrata Forms Setup. Or, the images can be imported directly into Xtrata Forms Setup as classification sample images. Refer to Definition Batches on page 46 for more information about creating definition batches. Refer to Moving Images to the Definition Folder on page 122 for more information about using the definition folder. 30 Getting Started with Ascent Xtrata

41 Setting Up Batch Classes with Ascent Xtrata Similarity When a new classification sample image is added to a sample or unassigned sample page in Xtrata Forms Setup, the similarity of the image is compared to existing sample images. If the similarity is lower than the value configured here, a warning is displayed. The value you choose depends on whether the forms to be processed are very similar or have very different physical layouts. For example, if similarity is set to 90%, but you attempt to add a new classification sample image that returns a similarity of 32%, this means that the new sample image is very different from existing samples. If the forms to be processed within the batch are very similar, you may not want to add that particular sample. The default value for required similarity is 90%. Refer to Additional Sample Images for Classification on page 36 for more information about adding sample images. Batch Class Considerations The following sections describe the requirements and limitations for batch classes that include Xtrata Server as a processing queue. Refer to your Ascent Capture documentation for details about Ascent Capture processing options. Separation and Form Identification If you use Xtrata Server, all document separation tasks will be performed by the Scan module or by Xtrata Server. All document separation options concerning Kofax page recognition in Recognition Server will be disregarded. Ascent Xtrata always creates separated documents for the recognition process. If you want Recognition Server to perform form identification for images that could not be classified with Xtrata Server, you can specify form identification options for the batch class. Create a custom separation and form identification profile or select the desired form identification method. Make sure to select the option Ignore classification errors in the Runtime tab of the Xtrata Settings for Batch Class dialog box (see Figure 3-4); otherwise, unclassified documents will be routed to Quality Control and not the Recognition Server module. For any documents unclassified by Xtrata Server, Recognition Server will use the specified identification method to perform form identification. You select these options from the Separation and Form Identification tab of the Batch Class Properties (or Create Batch Class) dialog box. Getting Started with Ascent Xtrata 31

42 Chapter 3 Document Separation by Xtrata If a batch contains only documents that are already separated during the scan process by patch code, bar code, fixed length, or any other method, Xtrata Server uses these documents for further processing and performs no further document separation. In contrast, if a batch contains loose pages created by the Scan module, Xtrata Server performs document separation. Loose pages may also be created manually in the Quality Control module. For these loose pages, documents are created when processed by Xtrata Server. Document separation in Xtrata Server uses classification to detect the start of a new document. Loose pages are classified one by one. If one of the loose pages is recognized as the first page of a form type, then a new document is created. Loose pages following the first one are classified and added to this document until another first page is detected. Xtrata Server checks the documents that are created for correct length. Xtrata can enforce the maximum length of a document with a fixed page count if the corresponding setting has been chosen in the Xtrata Settings dialog box of the batch class. (See Figure 3-4.) Documents must match the number of fixed pages of a form type set for the Fixed number of pages option of the form type properties in the Ascent Capture Administration module. Optionally, the sequence of pages in a document is checked using Xtrata classification technology. Black Border Removal It is recommended that you perform black border removal at scan time using a VRSenabled scanner. This is the fastest, most secure, and highest quality method to get clean, deskewed images for further processing. If this is not possible (for example, you are importing images or scanning with a non-vrs-enabled scanner), it is recommended that you perform black border removal in Xtrata Server. Refer to Settings on page 26 for more information about setting black border removal for Xtrata Server. While it is possible to configure black border removal with cropping as permanent image clean up in Ascent Capture, you should not use this Ascent Capture feature with Ascent Xtrata. Xtrata Server registers zones based on uncropped images, and the zones will not be positioned correctly if Ascent Capture changes the image size by cropping the image. 32 Getting Started with Ascent Xtrata

43 Setting Up Batch Classes with Ascent Xtrata Registration Since Xtrata Server performs registration on each page that has index zones defined, there is no need to specify registration settings or registration zones in Ascent Capture. Sample Pages For classification, all form types must have at least one sample page. Xtrata Server will not classify form types that do not have sample pages. Note When you publish a batch class that contains form types having no sample pages, a warning is displayed. You add a sample page by right-clicking the form type and selecting Add Sample Pages from the context menu. Figure 3-6. Add Sample Page in Context Menu Note In addition to the sample page, it is recommended that you use additional samples images for classification. Refer to Additional Sample Images for Classification on page 36 for more information about adding sample pages. Recognition Scripts Recognition Server will ignore OMR zones if they have been evaluated by Xtrata Server. Therefore, do not use recognition scripts for batch classes that use Xtrata Getting Started with Ascent Xtrata 33

44 Chapter 3 Server for OMR processing. Refer to OMR on page 27 for more information about enabling OMR processing for Xtrata Server. ACI Server Batch classes that include Xtrata Server can be used with Ascent Capture Internet Server. However, Xtrata Server must be set to run at the central site. The Xtrata Form Type Correction panel will only be available in Quality Control at the central site: It will not be available in Quality Control at the remote site. In addition, do not install Xtrata Server at your remote sites. For this release, Xtrata relies on files that are not downloaded with the batch classes when the remote sites synchronize with the central site. Ascent Ricochet Ascent Xtrata has not been certified with Ascent Ricochet. Therefore, batch classes that include Xtrata Server cannot be used with Ascent Ricochet. edocuments in Xtrata Server Xtrata Server handles edocuments in two ways, depending on whether a batch contains an edocument as part of a document or as a loose page. When an edocument is a part of a document, then it is passed through Xtrata Server. If it is present in the batch as a loose page, then Xtrata Server creates a document out of it and no form type is assigned. Publishing Batch Classes Once Xtrata Server is added as a processing queue and batch class, document class, and form type settings are defined, the batch class must be published for the settings to take effect. Ascent Xtrata settings are stored and managed like other batch class information in Ascent Capture. To publish a batch class 1 From the Administration module s Definitions panel, select the Batch class tab. 2 Right-click the batch class that you want to publish, and select Publish from the context menu. The Publish dialog box will display. 34 Getting Started with Ascent Xtrata

45 Setting Up Batch Classes with Ascent Xtrata 3 Click Publish. The publishing process checks your batch class selections, including any Ascent Xtrata-specific settings, and returns the results to the Results box. 4 Assess any warnings and correct them if necessary and republish if changes are made. If errors are found, you must correct them and republish. Xtrata Classification Sample Images Ascent Xtrata sample images are not stored and managed like other Ascent Capture settings. They are stored in their own internal structure, which is synchronized with Ascent Capture batch class data when batch classes that contain Xtrata Server are successfully published. Republishing a batch class and synchronizing the Ascent Xtrata data with Ascent Capture data does not impact batches in the system. The batches will be processed with the settings that were in place when the batches were created. Only new batches created after republishing will use the new settings. Warning Do not delete or alter the XtrataDB folder located in your Ascent Capture installation folder, or any of the items contained in it. Doing so will compromise your Ascent Xtrata installation and cause loss of data, and the results will be unpredictable. Importing/Exporting Batch Classes Batch classes that include Xtrata Server need an additional export step besides the Ascent Capture import/export feature if they include: Additional classification sample images Note When you export batch classes that contain Xtrata Server, the additional classification sample images or segmentation results from Xtrata Forms Setup and other information is not saved within the export cab file. No error or warning will display, but the exported batch class will not contain Ascent Xtrata data. You can use the export feature of Xtrata Forms Setup to export the additional Xtrata batch class information. Refer to Exporting/Importing Xtrata Batch Classes on page 104 for further information. Batch classes that do not include the above items can be exported from Ascent Capture. They can be imported to an Ascent Capture system where Xtrata Server is installed. They must be published before they can be used. Getting Started with Ascent Xtrata 35

46 Chapter 3 Additional Sample Images for Classification Ascent Xtrata uses the first sample page of each form type to learn the pattern of the form type for classification. For multipage forms, additional sample pages can optionally be used for checking the sequence of the document. Only form types that have at least one sample page can be classified with Xtrata Server. Form types without sample pages will be left as unclassified during Xtrata Server processing. In addition to the sample page, it is recommended that additional classification images be used. Adding Classification Sample Images Adding more classification sample images for a sample page results in superior classification quality without affecting performance. To enhance classification in Xtrata Server without negatively impacting performance, you should use, besides the sample page, from 4-9 classification sample images for each form type. Note You can add additional Ascent Xtrata classification sample images for sample pages of a form type as defined within Ascent Capture, and which are associated with a batch class that contains Xtrata Server as a processing queue. To add additional classification sample images 1 From the Administration module s Definitions panel, select the Batch class tab. 2 Select the batch class that you want to edit, and expand it to view its form types. 3 Right-click the sample page that you want to edit. A context menu for the sample page will display. Note The Add Classification Sample Images option (shown below) will only be available in the context menu if the selected sample page is associated with a batch class that includes Xtrata Server as a processing queue. If Add Classification Sample Images is not an option, verify that you selected the sample page of a form type from the desired batch class, and that the batch class includes Xtrata Server as a processing queue. Refer to Adding Xtrata Server to a Batch Class on page 22. You cannot add additional classification sample images if the form type does not have a sample page. If this is the case, right-click the Add Sample Pages option and add the desired sample page. 36 Getting Started with Ascent Xtrata

New classification sample images are listed with an internal name in blue color and marked with an asterisk. This allows you to easily find and validate the new classification sample images before you save them. Note When adding classification sample images, Ascent Xtrata compares the new samples with existing sample images for the form type. If the similarity of a new sample is below the defined similarity value, the following warning will display: The file file name has only a similarity of similarity%, compared with the existing sample images. Do you really want to add it? You can choose to add the new sample or discard it. Refer to Similarity on page 31 for information about defining the desired similarity threshold. 38 Getting Started with Ascent Xtrata

49 Setting Up Batch Classes with Ascent Xtrata Figure New Classification Sample Images in List Note If Xtrata Server will be used for classification and registration of index zones, it is recommended that you add only similar images for a sample page. This is because proper registration is only possible if the sample images have very similar layouts. However, if Xtrata Server will perform classification only, then using very similar sample images is not required. Refer to Classification only on page 27 for more information about setting Xtrata Server to perform classification only. 9 Click Apply to save your settings without closing the Classification Sample Images dialog box. Click OK to save your settings and close the dialog box. Saving your settings changes the color of the names used internally by Ascent Xtrata to black, and removes the asterisks from the list.

Note The Add Classification Sample Images option (shown in Figure 3-7) will only be available in the context menu if the selected sample page is associated with a batch class that includes Xtrata Server as a processing queue. If Add Classification Sample Images is not an option, verify that you selected the sample page of a form type from the desired batch class, and that the batch class includes Xtrata Server as a processing queue. Refer to Adding Xtrata Server to a Batch Class on page Select the classification sample image that you want to delete and click the Remove button ( ). Previously saved sample images will be marked with a red X to indicate that they are marked for deletion. Sample images that were not previously saved are immediately removed. This would be the case if you added a new sample classification image and then deleted it without saving it. Note You cannot delete the sample page that was added for the form type in Ascent Capture. The Ascent Capture sample page is always listed as the first sample page. The Remove button is not available if the Ascent Capture sample page is selected. 40 Getting Started with Ascent Xtrata

53 Chapter 4 Using Xtrata Forms Setup Introduction With Xtrata Forms Setup, an optimized user interface is provided for quick and easy forms set up using sample images and segmentation results from Xtrata processing. Xtrata Forms Setup is integrated and accessible from the Ascent Capture Administration module. Sample images and segmentation results can be set up for Xtrata Forms Setup in two ways. You can: Scan or import images with a special-purpose Xtrata definition batch class. This batch class has the purpose of importing new images and segmentation results from Xtrata processing to Xtrata Forms Setup. Similar images are clustered into an unassigned sample page with classification sample images. When at least five images exist in a cluster, segmentation is performed. Create new form types and sample pages, and add classification sample images directly in Xtrata Forms Setup. For these, manual segmentation can be initiated. Note Segmentation results can easily be updated. Refer to Manually Initiating Segmentation on page 82. This chapter describes how to use the advanced features of Ascent Xtrata, such as processing Xtrata definition batches and using Xtrata Forms Setup to facilitate form type set up and index zone definition. Getting Started with Ascent Xtrata 43

54 Chapter 4 Functionality Overview The Xtrata Forms Setup interface is available from the Ascent Capture Administration module to assist with form type set up and index zone definition. A form type is defined by various sample pages. Xtrata Forms Setup uses additional sample images to perform segmentation for the sample page. It can be used in conjunction with normal Ascent Capture methods for defining form types and zones during batch class definition. Xtrata Forms Setup displays all existing form types for the selected batch class and their sample pages and respective classification sample images. It allows you to assign sample pages to a form type and to add more sample images or delete sample images as desired. Segmentation can be performed if at least four sample images exist for a sample or an unassigned sample page. If segmentation has been performed, the results can be used for quick assisted index zone creation without having to draw the zones by hand. In addition, Xtrata Forms Setup allows you to create new form types, add new sample pages, add new classification sample images, add new index zones, and change the coordinates of any existing index zones. All items defined in Xtrata Forms Setup are stored with other Ascent Capture settings when Xtrata Forms Setup is closed. Note Only images with resolutions of 200 and 300 DPI are supported. Images with different resolutions in vertical and horizontal directions are not supported. For classification purposes, the classification sample images can be mixed (200 and 300 DPI), but sample images in both resolutions must be provided. If you want to use the segmentation functionality, you must provide images of the same resolution (either 200 or 300 DPI). Otherwise, you will get unpredictable results for registration and segmentation. You will not get a warning if you mix the resolution for registration. Typical Workflow Figure 4-1 illustrates a typical Ascent Capture workflow that includes Xtrata Server with batch classes set up using Xtrata Forms Setup. 44 Getting Started with Ascent Xtrata

55 Using Xtrata Forms Setup Figure 4-1. Typical Workflow with Xtrata Server Using Advanced Features In the example workflow, Xtrata Forms Setup is used from the Ascent Capture Administration module to set up form types and sample pages and define zones for batch classes that contain Xtrata Server as a processing queue. Once the batch class is published, batches can be scanned or imported into Ascent Capture, and then sent to Xtrata Server where Xtrata runtime processing occurs. Production batches closed from Xtrata Server are passed through the normal Ascent Capture workflow. Documents that cannot be classified, or have errors due to the number of pages or the document sequence, are routed directly to the Ascent Capture Quality Control module, where the Xtrata Form Type Correction panel can be used to manually classify forms. If the Undefined scanning option is enabled for the batch class, the images of the unclassified documents are copied to the specified folder for definition images. They can be automatically clustered by an Xtrata definition batch or manually added as new sample pages or sample images to a form type. Note If you select the "ignore... errors" option on the Runtime tab of the batch class properties, then the batch is not routed to Quality Control if an error of this type during Ascent Xtrata processing occurs. Getting Started with Ascent Xtrata 45

56 Chapter 4 Definition batches are created with the special-purpose definition batch class installed with Ascent Xtrata. You can import the definition batch class just like any other Ascent Capture batch class, publish it, and then use it to create definition batches. Definition Batches Ascent Xtrata allows you to scan or import definition batches that automatically prepare images and segmentation data for easy set up of sample pages. Definition batches use a special-purpose definition batch class that is installed with Ascent Xtrata. Xtrata Server processes definition batches in a different way compared to production batches. For definition batches, Xtrata Server automatically clusters similar images in a batch into an unassigned sample page with classification images, and performs segmentation as soon as four images exist for the unassigned sample page. The unassigned sample pages and segmentation results are automatically made available to Xtrata Forms Setup to facilitate setting up new sample pages for form types and defining index zones. Note It is recommended that you use Xtrata definition batches to cluster images and segment zones for easy forms set up. The name of the special-purpose definition batch class is XtrataDefinition. You can import this batch class into Ascent Capture from the Ascent Capture Export folder, publish it, and then use it to create definition batches. Note Do not change the name of the definition batch class. Xtrata Server identifies definition batches by the name of the batch class. Do not change any of the properties in the definition batch class. Specific properties are required for the definition batches to return the necessary data to Xtrata Forms Setup, and the properties have all been set in the definition batch class installed with Ascent Xtrata. Do not attempt to create your own definition batch class. If you do not use the definition batch class installed with Ascent Xtrata, the results from definition batch processing returned to Xtrata Forms Setup will be unpredictable. 46 Getting Started with Ascent Xtrata

57 Using Xtrata Forms Setup Importing the Definition Batch Class You can import the Xtrata definition batch class from the Ascent Capture Export folder. To import the definition batch class 1 From the Administration module s menu bar, select File Import. The Open dialog box will display. 2 If necessary, browse to the Ascent Capture Export folder. (Installing Ascent Xtrata installs the definition batch class to this folder.) Note If the definition batch class (XtrataDefinition.cab) is not available from the Ascent Capture Export folder, you must repair your Ascent Xtrata installation. Refer to Application Maintenance on page 15 for instructions on repairing your installation. 3 Select XtrataDefinition.cab and click Open. The Import/Export dialog box will display, and the contents of the cabinet file (cab file) will unpack. When the cab file is unpacked, the Import dialog box will display. Figure 4-2. Xtrata Definition as an Available Batch Class 4 Select XtrataDefinition from the list of Available Batch Classes and click Add. The batch class will move to the list of Selected Batch Classes. 5 Select Replace duplicates with items imported for the Transfer Mode. This mode overwrites existing batch class items during the import process, if they have the same names as imported items. Getting Started with Ascent Xtrata 47

58 Chapter 4 Note The names of the definition batch class and the items it contains must be as installed by Ascent Xtrata. If you use Save duplicates to a new name for the Transfer Mode and any existing items use the same names, the imported items will be renamed. The renamed batch class will be ignored by Xtrata. If you want to refresh the definition batch class, choose Replace duplicates with items imported. The existing definition batch class will be overwritten with the imported batch class, and the batch class items will retain their original names. 6 Click Import. the Import/Export dialog box will display, and the progress will display in the Import Progress area. 7 When the import is complete, click OK. 8 The batch class XtrataDefinition is imported and displayed as a new batch class in the Administration module s Definitions panel (Batch tab). After publishing, the batch class is available for processing definition batches. Figure 4-3. Definition Batch Class in Definitions Panel Xtrata Settings for Definition Batch Class Once you import the definition batch class, you can specify Xtrata settings for definition batch processing. You do this by selecting Xtrata Settings from the context menu for the definition batch class. The settings are specific to the definition batch class. Note The Xtrata Settings option is available for all batch classes that include Xtrata Server as a processing queue. However, the Xtrata settings available for the definition batch class are slightly different from those for batch classes that you create. 48 Getting Started with Ascent Xtrata

(This is the Xtrata definition batch class.) The context menu for the batch class will display. 3 From the context menu, select Xtrata Settings. The Xtrata Settings for Definition Batch dialog box will display. (See Figure 4-4.) The options available from this dialog box are described in the following sections. Runtime Tab The option on the Runtime tab allows you to specify a confidence threshold for form classification during definition batch processing in Xtrata Server. Figure 4-4. Xtrata Settings for Definition Batch Runtime Tab Classification The Classification area provides a slider that allows you to set the absolute confidence required for confident clustering and classification of images during Xtrata Server definition batch processing. Minimum confidence This is the absolute confidence required for classification by Xtrata Server. Valid values are from 0% to 100%. The default value is 70%, which is recommended for high quality and very low error rates for typical forms. Higher values can increase over-classification and cause more unassigned sample pages than necessary to be created. The recommended value is 70%. Only images that are classified and exceed the minimum confidence are added as new samples to an existing unassigned sample page in Xtrata Forms Setup. For images that do not exceed the threshold for any existing unassigned sample page, a new unassigned sample page is created. Getting Started with Ascent Xtrata 49

60 Chapter 4 Setup Tab The Setup tab allows you to specify the storage location for definition batch images after they are processed by Xtrata Server. The images are saved to this location before the batches are deleted. Figure 4-5. Xtrata Settings for Definition Batch - Setup Tab Folder for images to reimport This is the storage location for definition batch images. If Xtrata Server is set to remove definition batches after they are processed by Xtrata Server, the images from the batch are stored in the specified storage location before the batches are deleted. These images can subsequently be re-imported in a production batch. This allows images that have been used in definition batches to be processed in production batches without scanning them again. The default path is \ReImport in the Ascent server path. Note This location is ignored if Xtrata Server is set to retain batches after processing them. Enabling and disabling the batch deletion behavior is an option available from the Xtrata Server Tools menu. See Chapter 5 for details about the Xtrata Server menu options. Processing Definition Batches When processing definition batches, Xtrata Server automatically clusters similar images into unassigned sample pages with classification sample images. As soon as at least five images exist in a cluster, Xtrata Server performs segmentation to locate the field areas on the form. Then, it saves the segmentation and image information to the Xtrata database so that it is available to Xtrata Forms Setup. You can use Xtrata Forms Setup to set up new form types and zones based on the images and segmentation data from Xtrata Server definition batch processing. 50 Getting Started with Ascent Xtrata

61 Using Xtrata Forms Setup Note Segmentation may take several seconds per image. In addition, only singlepage documents are supported by Ascent Xtrata. By default, definition batches are removed from the system as soon as they are processed by Xtrata Server. However, the image files are always saved. If Xtrata Server is set to delete definition batches after processing, the image files are stored in the folder for images to re-import. This folder is specified on the Xtrata Settings for Definition Batch dialog box (Setup tab). See Setup Tab on page 50. If Xtrata Server is set to retain definition batches after processing (that is, the batch deletion option is disabled), the image files remain in the Ascent Capture images folder specified for the definition batch class. If desired, images from definition batches can be used to create production batches, once the appropriate form types have been added to production batch classes. This allows you to process the images from the definition batches in production batches without rescanning the images. Note For definition purposes, images should be processed in no more than one definition batch. If you process the same images in more than one definition batch, the sample pages will be generated for each definition batch and multiple copies of the same images will be generated. Recommendations for Definition Batch Processing Image Preprocessing and Quality Note the following important recommendations concerning image quality, preprocessing and resolution: High quality images are recommended for definition batches. The images can be scanned darker and with higher contrast than production scanning to provide the clear lines needed for field detection and automatic segmentation. If lines are too broken due to light scanning, segmentation will fail. Deskew is recommended for optimal image quality. Black borders (if any) must be removed at scan time. Images with black borders will yield inconsistent definition results. It is recommended that you perform black border removal at scan time using a VRS-enabled scanner. This is the fastest, most secure, and highest quality method for getting clean deskewed images. If this is not possible (for example, you are importing images or scanning with a non-vrs-enabled scanner), it is recommended that you perform black border removal in Xtrata Server. Refer Getting Started with Ascent Xtrata 51

62 Chapter 4 to Runtime Tab on page 24 for more information about enabling black border removal for Xtrata Server. It is recommended that you use images of same resolution (DPI). The supported resolutions are 200 and 300 DPI. Images with different resolutions in the x and y directions are not supported. Note Black border removal is always enabled for the definition batch class (XtrataDefinition). No black border removal option is available from the Xtrata Settings for Definition Batch dialog box (see Figure 4-5). In addition, while it is possible to configure black border cropping as permanent image cleanup in Ascent Capture, you should not use this feature with Ascent Xtrata. Xtrata registers zones based on uncropped images, and zones will be misaligned if the image size is changed by cropping the image. Segmentation To improve segmentation, it is possible to add an empty form that has not been filled to the definition batch. Structures such as very small check boxes and combs will be better identified if an empty form is used. However, the empty form should not be placed as the first image since the first image will be used as the sample page. The sample page should contain filled fields because it is also used to set up the recognition settings in Ascent Capture Administration. Please note that zones on the forms that are indicated by lines are only detected if at least three images contain variable content in the respective location. Multipage Forms It is not possible to process multipage forms in the definition batch and provide the complete multipage form type in Xtrata Forms Setup. Instead, a multipage form will be separated into single pages and each sample page will be clustered individually. If the pages are similar, you will receive one cluster as an unassigned sample page having classification sample images for each page of the multipage form. You can then recombine all unassigned sample pages to one form type using Xtrata Forms Setup. Note No special batch preparation is necessary for the samples used in definition batches. You do not need to sort the pages. Normally the fields on the samples should be filled in and not left empty. If available, you can also add an empty form as a sample image to the definition batch to improve segmentation results. In addition, you should use at least four classification sample images for a sample page in the definition batch; otherwise, no segmentation is possible. 52 Getting Started with Ascent Xtrata

63 Using Xtrata Forms Setup To create and process a definition batch 1 Click Start Programs Ascent Capture Scan to start the Scan module. 2 If batches are ready for processing at Scan, the Open Batch dialog box will display. If it does, click Cancel to close it. Then, from the menu bar, select Batch New to display the Create Batch dialog box. If no batches are ready for processing at Scan, the Create Batch dialog box will display. 3 From the General tab, select XtrataDefinition for the batch class. 4 If desired, specify a name for the batch. By default, the batch name is the date and time. 5 Click Scan. If you are scanning, the pages in your scanner will be scanned. If you are importing, the Import dialog box will display. Select the desired images and click Open. 6 Xtrata Server will take about 5 to 10 seconds per sample page to perform clustering and segmentation. The results are made available as unassigned sample pages to Xtrata Forms Setup. Note The images of a definition batch are removed from the Ascent Capture workflow as soon as they have been moved to Xtrata Forms Setup as unassigned sample pages. However, a copy of the images is made into a folder for reimport that can be defined in the settings for the definition batch. See Definition Batches on page 46. Xtrata Forms Setup Xtrata Forms Setup is a custom interface added to the Ascent Capture Administration module when you install Ascent Xtrata. It allows you to quickly and easily set up form types, sample pages and define zones. You can create and delete form types, add and delete sample pages and classification sample images, and manage zones directly from Xtrata Forms Setup. Starting Xtrata Forms Setup You start Xtrata Forms Setup from the context menu of a batch class that contains Xtrata Server as a processing queue and has at least one document class associated with it.

(Refer to Similarity on page 31 for more information about the similarity setting.) 4 Click OK to save the images and close the Add Classification Sample Images dialog box. 5 If the selected image contains multiple pages (for example, a multipage tiff), then click Yes to insert each page of the image file as a single classification sample image. Click No if you want to insert only the first page as classification sample image. Note Add at least five sample images (a sample page plus four sample images) if you plan to perform segmentation. Make sure that you use images that are based on exactly the same form but are filled differently. Even slight variations of the form template of the sample images will have a negative impact on automatic segmentation. In addition, do not add the same image more than once. Ascent Xtrata performs a statistical analysis to find constant background information over all sample images, so having the same image multiple times in your set of sample images will yield unpredictable segmentation and background removal results. Getting Started with Ascent Xtrata 71

82 Chapter 4 Perform Segmentation You can perform segmentation for any sample page with at least five sample images (the sample page plus four sample images). Segmentation requires at least five samples, but uses a maximum of ten sample images. If fewer than five sample images are available, the Perform Segmentation context menu option will be disabled. If more than ten sample images are available, the segmentation process will use the first ten samples and ignore the rest. Note For classification, all sample images (sample page plus all sample images) are taken into account. To perform segmentation 1 Right-click the sample page from the Ascent Capture Form Types pane or the Unassigned Sample Page pane and select Perform Segmentation from the context menu. Segmentation can take up to 5-10 seconds per image. Note The sample page for a form type is counted as a sample image. To perform segmentation, five samples (one sample page plus four sample images) must be available. When segmentation is complete, the check box in the Segmentation column for the sample page is checked as shown as Figure Figure Perform Segmentation Note Segmentation results for an unassigned sample page cannot be viewed. You must assign the sample page to a form type, before you can display and accept segmentation zones. Refer to Tools for Adding Index Zones on page 88 for more information. 72 Getting Started with Ascent Xtrata

83 Using Xtrata Forms Setup Merge Unassigned Sample Pages In some cases, similar images might be placed in different unassigned sample pages because they were processed in two different definition batches. If desired, you can merge an unassigned sample page to another unassigned sample page. That means that the selected unassigned sample page with all dependent classification sample images are added to the unassigned sample page as classification sample images. To merge unassigned sample pages 1 Right-click on a sample page in the lower pane to display the context menu and select the item Merge Unassigned Sample Pages. Figure Merge Unassigned Sample Pages in Context Menu A dialog box is displayed with a combo box that contains all other unassigned samples pages from the list of unassigned sample pages.

84 Chapter 4 Xtrata Form Type Properties Xtrata Forms Setup allows you to set some additional processing options, such as background removal, check all pages, and reorder pages. These options can be selected from the Xtrata Form Type Properties dialog box. To open the properties dialog box for a form type, select the form type and choose the Properties menu item, or right-click the form type and select Properties from the context menu, or click Edit Properties from the toolbar. The settings can also be set directly in the Ascent Capture Form Types pane by left-clicking the appropriate check box for a form type. Figure Xtrata Form Type Properties Background Removal Ascent Xtrata provides the ability to work with forms for which background items (such as lines or combs within zones) are removed temporarily for character recognition. This can improve recognition results by allowing you to process zone data without field structures. Background removal can be activated for all form types with at least one sample page having segmentation results available. If segmentation results are available, a check mark is displayed in the Segmentation column for the sample page. See Figure 4-25 on page 72. To perform segmentation, right-click the sample page and select Perform Segmentation from the context menu. For form types for which background removal is activated, you can switch back and forth between sample pages with and without visible background items. To activate background removal 1 Right-click the form type having at least one sample page with segmentation results and select Properties from the context menu. 74 Getting Started with Ascent Xtrata

85 Using Xtrata Forms Setup 2 A dialog box is displayed for activating or deactivating background removal. 3 Alternatively, you can left-click directly on the check box in the column Background Removal to activate or deactivate background removal. Working With Dropped Out Image If background removal is activated for a form type, the option Work on Dropped Out Image is added to the context menu of a form type in the Ascent Capture Administration module if at least one sample page is available having segmentation results. By selecting this option, background removal is executed for all defined index zones on the sample pages of the form type having segmentation results. You can use this for testing OCR results for the image. During publishing of the batch class, the image is substituted automatically by the original sample page. You can also do this manually by the context menu Load Original Sample Page of the form type. To work with dropped out image 1 In Xtrata Forms Setup, verify that segmentation results are available for the sample page, and that background removal is activated for the form type. Close Xtrata Forms Setup and right-click on the same form type in the Ascent Capture Administration module. Select Work on Dropped Out Image from the context menu. 2 The background is removed for all sample pages where segmentation results are available and for all regions on the sample page where index zones are defined. To load original sample page 1 Right-click on the form type in the Ascent Capture Administration module. Select Load Original Sample Page from the context menu. 2 The original sample pages are reloaded. Check All Pages When this option is set, Xtrata Server verifies that the pages of a document are in the correct sequence as defined by the order of the form type s sample pages. If only one sample image per sample page is available, this image will be used for matching. If additional sample images are available for a sample page, the current page is matched with all additional sample images. If the matching step detects an error in the sequence, Xtrata Server flags the document for Quality Control (based on the error handling options) and adds the note Document pages are out of sequence to the page. Getting Started with Ascent Xtrata 75

86 Chapter 4 To activate the Check all pages option 1 In Xtrata Forms Setup, right-click the form type and select Properties from the context menu. 2 A dialog box is displayed for activating or deactivating the Check all pages option. 3 Alternatively, you can left-click directly on the check box in the column Check All Pages to activate or deactivate this option. Reorder Pages For reordering, Xtrata Server examines all pages of a document and checks their order according to the order and number of the sample pages if the option Check all pages is enabled. If the matching step detects an error in the sequence of the pages, an error correction step is applied that tries to reorder the pages based on the matching results with all sample pages. If they cannot be reordered, an out of order error is raised. To activate the Reorder pages option 1 In Xtrata Forms Setup, right-click the form type and select Properties from the context menu. 2 A properties dialog box is displayed for activating or deactivating this option. You have to enable Check all pages first, before you can activate Reorder pages. 3 Alternatively, you can left-click directly on the check box in the column Reorder Pages to activate or deactivate it. Classification Sample Images and Sample Pages When an image is added as a sample image to an existing sample page, Xtrata checks the similarity of this image with the existing images. If the similarity is lower than required by the minimum similarity specified in the Xtrata Settings for Batch Class dialog box (Setup tab), a warning is issued. You can then either skip the image or add it. If you set the similarity to 0, the similarity check is skipped and the image is added without further warning. Classification sample images added in Xtrata Forms Setup are not visible in Ascent Capture, with the exception of the sample page. The sample page will be visible for the form type in the Ascent Capture Definitions panel. 76 Getting Started with Ascent Xtrata

87 Using Xtrata Forms Setup Once classification sample images are added, you can move them into assigned or unassigned sample pages, and replace the sample page with a different sample image. Re-organize Unassigned Sample Pages You can re-organize unassigned classification sample images using the mouse, by dragging them to another unassigned sample page within the list of Unassigned Sample Pages in the lower pane of Xtrata Forms Setup. If you drag and drop a sample image, it is added to the target unassigned sample page as a new classification sample image. If you drag and drop an unassigned sample page onto another unassigned sample page, they are merged. In this way, the selected sample page, as well as all of the associated classification sample images are added as new sample images to the target unassigned sample page. To move classification sample image to another unassigned sample page 1 From the list of Unassigned Sample Pages in the lower pane, drag the desired classification sample image to the target unassigned sample page and drop it. A similarity check is performed for each image based on the defined settings for the batch class. (Refer to Similarity on page 31 for more information about the similarity settings.) If the new image does not match the existing images within the required similarity, a warning is displayed. You can either override the warning or cancel the operation. 2 The new sample image is added to the target unassigned sample page as a classification sample image at the end of the classification sample image list. To merge unassigned sample pages 1 From the list of Unassigned Sample Pages in the lower pane, drag the sample page to the target unassigned sample page and drop it. A similarity check is performed for each image based on the defined settings for the batch class. (Refer to Similarity on page 31 for more information about the similarity setting.) If any of the new images do not match the existing images within the required similarity, a warning is displayed. You can either override the warning or cancel the operation. 2 The new sample images are added to the target unassigned sample page as classification sample images.

89 Using Xtrata Forms Setup Defining Index Zones in Xtrata Forms Setup Xtrata Forms Setup is especially optimized to create index zones on a form. Although index zones can also be created in Ascent Capture directly, Xtrata Forms Setup makes it easy to set up a form because zone coordinates are available from segmentation results. In Xtrata Forms Setup, you can set up the geometrical properties and the assigned recognition profile of a zone. All other settings, such as editing a recognition profile or adding image preprocessing methods, must be done in Ascent Capture Administration. Ascent Xtrata uses a slightly different approach for creating new index zones compared to Ascent Capture. While in Ascent Capture a new index zone must be assigned immediately to an index field, this is not the case in Xtrata Forms Setup. Since Xtrata Forms Setup allows the creation of multiple index zones at once, the zones can exist on their own until they are assigned to an index field. Therefore, the creation of an index zone and the assignment to an index field are two distinct steps in Xtrata Forms Setup. Xtrata can identify three different types of zones: Segmentation zones: Results of segmentation are depicted as solid filled rectangles. These zones are normally not visible and only used for highlighting found zonal areas. Unassigned zones: New zones that have been created manually or by accepting segmentation results. These zones are depicted as rectangles with a thick solid border. Assigned zones: Zones that have been assigned to an index field are depicted with dashed borders. Assigned zones are either index zones that have been saved to Ascent Capture or have been recently assigned to an index field. The index zones are stored to Ascent Capture when the form type is saved from Xtrata Forms Setup. Automatic Segmentation Automatic segmentation is a term that describes the generation of index zone geometries from sample images. For this algorithm, Xtrata generates statistical information from all sample images of a sample page. The lines, boxes, and preprinted text are analyzed to find the regions of interest and the exact geometries of the objects on the forms. Hand printed information from filled-in forms is eliminated, while the position and the area of the filled region are retained for forms analysis. Ascent Xtrata identifies these areas as segmentation zones, which can be accepted as index zones by the user and assigned to index fields for Ascent Capture processing. Based on the forms analysis, Ascent Xtrata identifies zone coordinates, zone types, and zone labels. The information is saved for further processing steps, such as registration and background removal. Especially for background removal, the quality Getting Started with Ascent Xtrata 79

90 Chapter 4 of the cleaned images is enhanced greatly by using the statistical information from segmentation. Segmentation uses various assumptions about the found elements on the form. Besides labels and other pre-printed information, zones are detected as one of the following zone types: Boxes A box field is a printed rectangle on the form. Often, the label for the field is printed inside of the box in the upper or lower left corner. A box field is marked in dark blue in the Xtrata Forms Setup viewer. Figure Box Field Lines A line field is common on forms that force users to use constrained areas for hand printed data. The label of a line is either to the left or below the line. A line field is marked in light blue in the Xtrata Forms Setup viewer. Figure Line Field Comb Areas A comb is used to force the user to use constrained block hand printed letters or numbers. The ticks are normally equidistant. A comb can be open (like the example shown below) or closed when the tick marks touch the upper border. A comb is marked in green in the Xtrata Forms Setup viewer. Figure Comb Field 80 Getting Started with Ascent Xtrata

91 Using Xtrata Forms Setup Check Boxes Check boxes are small rectangles used to capture binary Yes/No information. Circular check marks are not supported. A check box is marked in red in the Xtrata Forms Setup viewer. Figure Check Boxes The type of a segmentation zone is displayed as a tool tip of the zone. Move your mouse cursor over a segmentation zone in the Xtrata Forms Setup viewer to display the label and the type of the zone as text. Assigned index zones are displayed in the same fashion as in Ascent Capture, in light green with a dashed border. The index field assigned to the index zone is displayed as a tool tip. By moving your mouse cursor over an assigned zone in the Xtrata Forms Setup viewer, the index field of the zone is displayed as text. Note Ascent Xtrata's segmentation feature automatically detects the following structures: boxes, lines, combs and check boxes. Segmentation works best if you provide high quality images of exactly the same type without noise and skew. Ascent Xtrata will not detect circular fields (circular and oval check mark regions). If a field area is designed as a series of unconnected boxes or combs (for example a 10- digit telephone number designed as 10 individual small boxes), it may be detected as a set of multiple fields of type box or comb rather than a single field. You can manually extend one of these boxes to cover the complete region. In any case, if Ascent Xtrata misses a structure, you can manually draw a zone and use any combination of manually drawn zones, manually changed segmentation zones, and original segmentation zones. It is important to understand that registration is independent of segmentation, so it works as well for manual zones as it does for zones detected by segmentation. Segmentation is performed either by Xtrata Server processing a definition batch, or by Xtrata Forms Setup when started manually for a sample page. If segmentation provides useless results, then either the image quality was not good enough or the forms were not similar. You must use similar forms that are filled in differently to achieve good segmentation results. Only the first ten sample images of a form type are used for segmentation. To improve segmentation, you can replace the images with Getting Started with Ascent Xtrata 81

92 Chapter 4 images of higher quality. For the recognition of small structures such as check boxes or combs, you can improve the results by adding an empty, unfilled form. For segmentation only the first ten images are used. If you add more, those will only be relevant for the classification. Note Sample images that are used for forms segmentation need not be blank but can be filled by hand printed information. Ascent Xtrata uses advanced statistical methods to distinguish filled-in information from the preprinted form background. The preprinted information is separated and used for identification of zones and check boxes. Some zone types, such as fields that are only marked by a line, require at least some of the sample images to have hand printed information in the zone location. If this is not the case, index zones can be added manually. If small structures such as check boxes or combs are not correctly segmented, you might try to add an empty, unfilled form of the same type if one is available. Make sure that you do not add the empty form as the first sample image because the first image is used as the sample page. The sample page is used in the Ascent Capture Administration module to define the recognition settings for each index zone. Manually Initiating Segmentation Segmentation automatically occurs during definition batch processing, as soon as at least five sample images are clustered for a sample page. You can also initiate or redo segmentation for a sample page in Xtrata Forms Setup. To manually initiate segmentation 1 From Xtrata Forms Setup, select a sample page with at least four classification sample images. 2 Open the context menu for the sample page by right-clicking on the sample page and selecting Perform Segmentation. 3 If segmentation results are already available for the selected sample page, a message will display prompting whether you want to renew the existing segmentation data. Click Yes to renew the existing segmentation data. 4 Segmentation is processed for the images, and segmentation zones are available for the sample page. 82 Getting Started with Ascent Xtrata

93 Using Xtrata Forms Setup Note The segmentation algorithm finds zone boundaries exactly on the preprinted structures of a sample page. Normally, the filled-in data is written over the lines so it is recommended that index zones be larger than the preprinted zones. This is also important for background removal, since this algorithm only removes structures inside the zones. Therefore, the ability to resize multiple zones at once is very useful. See Move/Resize Zones in Xtrata Forms Setup Viewer on page 93. To manually delete segmentation 1 Right-click the sample page either from the Ascent Capture Form Types pane or the Unassigned Sample Page pane and select Delete Segmentation from the context menu. After segmentation is deleted, the check box in the Segmentation column for the sample page is unchecked and the unassigned index zones are deleted for the sample page. The segmentation results already assigned to an index field are not deleted. Figure 4-33 shows that all segmentation zones for an assigned sample page are deleted: Only the assigned index zones are kept. Figure Delete Segmentation for an Assigned Sample Page Note Segmentation results for unassigned sample pages are not displayed in the Xtrata Forms Setup viewer because you cannot assign the segmentation zones without knowing the index fields from the document class. Getting Started with Ascent Xtrata 83

94 Chapter 4 Setting Default Recognition Profiles and Field Types The segmentation process creates index zones of different zone types as described above. Refer to Automatic Segmentation on page 79 for more information. To perform recognition on index zones, a recognition profile must be assigned to the index zone. When an index field is created from an index zone, a field type is associated with this field. In many cases, the zone type detected by segmentation can be used to select the correct recognition profile. For example, check boxes will be evaluated by recognition profiles with OMR recognition, while combs normally contain constrained hand printed information to be read by zonal ICR. You can set a default recognition profile and a field type for each detected segmentation zone type using the Defaults for Segmentation Zone Types dialog box that can be called from the Tools menu. Figure Defaults for Segmentation Zone Types Dialog Box The dialog box displays a table with three columns and one line for each segmentation zone type. In the first column, the five zone types are listed together with their color code. The second column shows the default recognition profile that is assigned to an index zone when it is created from a segmentation zone. Click on any recognition profile entry to open a drop-down list that lets you select from all recognition profiles. The third column shows the default field type that is applied when an index field is created from this index zone. Click on any field type entry to open a drop-down list that lets you select an item from all field types. When you open the dialog box the first time, the two columns are empty. Once you select the default profiles, the settings are stored permanently. To define a default recognition profile 1 In Xtrata Forms Setup, select the item Default for Segmentation Zone Types from the Tools menu in the main menu bar. The dialog box is displayed. 84 Getting Started with Ascent Xtrata

Then, click OK to make the changes permanent and close the dialog box. Xtrata Forms Setup Viewer The Xtrata Forms Setup viewer displays the currently selected sample page and all assigned index zones or the selected classification sample image. It also allows you to view detected segmentation zones on sample pages, and use tools to accept or delete the zones. When you only select a form type in the Ascent Capture Form Types pane, the viewer displays nothing. The viewer offers standard tools for zooming and panning the displayed image and to facilitate finding and analyzing zones. For zones selected in the viewer, a context menu allows access to the Zone Properties dialog box. The properties allow you to resize and move the zones on the sample page, and select a recognition profile for the zones. (From Xtrata Forms Setup, you cannot change the recognition profile assigned to zones that have already been saved to Ascent Capture.) Getting Started with Ascent Xtrata 85

96 Chapter 4 The Xtrata Forms Setup viewer offers three useful shortcuts available from the keyboard and the mouse for zooming and positioning the image: Zoom with wheel: If you use a pointing device with a scroll wheel, you can use the wheel to zoom in and out of the current image. Pan with mouse: Holding down the shift key while pressing the left mouse button changes the mouse pointer in the viewer to a hand symbol. You can use the pointing device to move the image while you keep the left mouse button pressed. Arrow keys: Arrow keys pan the image in the viewer left, right, up, and down while the viewer is selected.

107 Using Xtrata Forms Setup Assign and Change Index Zones and Index Fields With Xtrata Forms Setup, index zones that are created on a sample page are not immediately assigned to an index field. Instead, to use the index zones for captured data during batch processing, you must assign index fields to them. You can assign index fields created in Ascent Capture for the document class to which the sample page of the form type belongs, or index fields defined in Xtrata Forms Setup. The Assign Index Zones dialog box allows you to assign unassigned index zones to index fields. Figure Assign Index Zones Dialog Box The Assign Index Zones dialog box is divided into three panes: The left pane lists Ascent Capture Index Fields for the document class to which the form type belongs, along with their associated field types. If desired, you can change the field type for an index field. Just click the name of the field type to display a dropdown list of field types, and select the desired field type. (Use a click again by pressing the left mouse button a second time on the same item with a little delay.) All field types defined in Ascent Capture are available from the drop-down list.

You can view the location of the zone from the Xtrata Forms Setup viewer. (Selecting an unassigned index zone from the Unassigned Zones list causes the corresponding zone to display as selected in the viewer.) 4 Click on the left-arrow button with an asterisk ( ) to create a new index field for the selected index zone. Alternatively you can double-click on an index zone or a group zone on the right side of the dialog box to create a new index field and assign the zone to it. 5 The new index field is added in the left list using the zone label as name for the new field. The index zone item is added to the Assigned Zones list in the middle pane. A default field type is assigned to the new index field. Exporting/Importing Xtrata Batch Classes Ascent Xtrata uses additional setup information (such as classification sample images and segmentation data) that is not stored inside the Ascent Capture database. Therefore, when exporting and importing Xtrata batch classes, you cannot follow the standard Ascent Capture methods alone. Carefully follow the procedures in the sections below for exporting and importing Xtrata batch classes. 104 Getting Started with Ascent Xtrata

115 Using Xtrata Forms Setup Exporting Xtrata Batch Classes Exporting an Xtrata batch class requires two general steps. You must export the batch class from Ascent Capture, and then export the additional Xtrata setup information from Xtrata Forms Setup. To export an Xtrata batch class 1 Export the Xtrata batch class from Ascent Capture. a From the Ascent Capture Administration module, select Files Export to display the Export dialog box. b Select the Xtrata batch class that you want to export and click Add. The batch class you selected will move from the list of Available Batch Classes to the list of Selected Batch Classes. c Click Save As to select the desired path and file name for the exported cab file. d Click Export to export the batch class. Refer to your Ascent Capture documentation for details about the Ascent Capture batch class export feature. 2 Export additional setup information from Xtrata Forms Setup. a From the Administration module s Definitions panel, right-click the Xtrata batch class that you exported with the Ascent Capture export feature. Then, select Xtrata Forms Setup from the context menu. b From Xtrata Forms Setup, select Tools Export Batch Class to display the Browse for Folder dialog box. c Select the path where you want the Xtrata data to be copied. Then, click OK to start the export. The Xtrata export process starts immediately. It creates a folder in the location you specified with the same name as the batch class and a subfolder named Classes. All additional batch class information is stored in the subfolder Classes. Getting Started with Ascent Xtrata 105

116 Chapter 4 Importing Xtrata Batch Classes Importing an Xtrata batch class requires two general steps. You must manually copy the exported Xtrata setup information to the XtrataDB folder, and then import the Xtrata batch class to Ascent Capture. Carefully follow the steps below when importing an Xtrata batch class. Note that you must only import the Xtrata batch class one time, and you must select a specific transfer mode for the Ascent Capture import process. To import the Xtrata batch class 1 Copy the contents of the Classes subfolder created during the Xtrata export process to the Classes subfolder of XtrataDB. XtrataDB is located in your Ascent Capture installation location. The Classes subfolder contains the additional Xtrata setup information (one subfolder for each form type with a unique identifier linked to the form type in Ascent Capture). 2 Import the Xtrata batch class. a From the Ascent Capture Administration module, select Files Import to display the Open dialog box. b Select the cab file for the exported Xtrata batch class, and click OK when the unpacking process is complete. c From the Import dialog box, select the Xtrata batch class and click Add. The batch class will move from the list of Available Batch Classes to the list of Selected Batch Classes. d Select Replace duplicates with items imported as the Transfer Mode and click Import. Warning Make absolutely sure that you select Replace duplicates with items imported as the transfer mode, when importing Xtrata batch classes. If you use a different transfer mode, your Xtrata processing results will be unpredictable, because a copy of all objects in the batch class will be created in Ascent Capture, but the form type and sample page objects will still be related to the same Xtrata directories. Therefore, two Ascent Capture sample pages will reference the same sample page information of Xtrata. e Click OK when the import process is complete. 106 Getting Started with Ascent Xtrata

117 Chapter 5 Processing Batches Introduction Xtrata Server is a custom module that can be added to the list of selected queues of an Ascent Capture batch class. Xtrata Server is typically placed just after the Scan module and before the Recognition Server module in the workflow. Xtrata Server runs as an unattended module. For production batches, it performs document separation, classification of images and registration of zones, and then passes the batches to the next queue in the workflow. Recognition Server is typically used after Xtrata Server to perform automatic data capture (such as OCR, ICR, bar code recognition, and others) and optional form identification. Refer to your Ascent Capture documentation for details about recognition technologies supported by Recognition Server. Whether a batch should be routed to Recognition Server or to the Quality Control module if Xtrata Server raises classification or document consistency errors is determined by the Xtrata error handling settings of the batch class. By default, Xtrata Server sends documents to the Quality Control module if an error in classification or document separation occurs. However, Xtrata Server can be set to ignore these errors and send batches that contain unclassified documents to Recognition Server for further processing. Note that Recognition Server is not required if Xtrata Server is used only for classification purposes. For definition batches, Xtrata Server clusters images into sample pages and automatically performs form segmentation when at least five images exist in a cluster. The unassigned sample page and segmentation data is made available to Xtrata Forms Setup in the Ascent Capture Administration module to facilitate form type and index zone definition. Then, the definition batches are deleted from Ascent Capture. Xtrata Server does not pass definition batches to any other queue in the Ascent Capture workflow. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for information about definition batches and Xtrata Forms Setup. Getting Started with Ascent Xtrata 107

118 Chapter 5 Processing Batches with Xtrata Server Batches for Xtrata Server can be created like any other Ascent Capture batch. You can create them in the Scan module, or you can create the batches in Batch Manager and then use Scan to scan or import documents. The images must have the same resolution as the images used as sample images for Xtrata. When closed from Scan, the batch is then routed to Xtrata Server. Xtrata Server classifies each single image in the batch and performs document separation. If the image can be associated with a first sample page of a form type, a new document with this form type is created. Subsequent images are added to this document until another image matches the first page of any form type. Note that there can be exceptions to this behavior if a default form type is defined or the option to enforce fixed length of documents is enabled. Refer to Runtime Tab on page 24 for more information. In addition, Xtrata Server registers the index zones and performs various optional runtime functions, such as automatic rotation, background removal, and optical mark recognition (OMR). For multipage documents, all zones on all pages are registered. The length of documents and the sequence of pages within a document can be checked by Xtrata Server. Optionally, Xtrata Server can reorder documents with pages that are out of sequence if possible. Color images are dynamically binarized in Xtrata Server in the same way as in Recognition Server. For multipage documents, each color page is binarized and saved as a bitonal image. The next module after Xtrata Server is typically Recognition Server, which makes use of the already determined form types and the zonal registration performed by Xtrata Server. If Xtrata Server cannot confidently classify a document, it leaves the document unclassified. This means that the document has no form type assigned. For this case, Recognition Server can try to classify this document using form identification. If you want to use Ascent Capture s form identification in addition to Xtrata classification, you can do this by defining the necessary form identification zones in Ascent Capture and setting the Separation and Forms Identification method to Kofax page recognition for the batch class. If an image is then left unclassified by Xtrata Server, it will be classified by the Recognition Server. This is applicable, for example, if two forms are very similar but can be distinguished by a form id. Xtrata will have both form types high in confidence so that the relative difference required for secure classification will be too small. Recognition Server will use page recognition to identify the form by a forms id. You have to set the page-level forms identification confidence to 0 in the form identification and separation profile of the form type. 108 Getting Started with Ascent Xtrata

119 Processing Batches Note It is recommended that you set the page level registration confidence to 0 for all form types in a batch class containing Xtrata Server. This value can be set in the properties for the form type in Ascent Capture. Just right-click the form type from the Administration module s Definitions panel and select Properties. The setting is on the Images tab. If this is not done, Recognition Server will try to register the image a second time, which will slow down the system. Xtrata Server can also be used for image classification only. For this case, no automatic index fields are defined for the form type and Recognition Server is not added to the workflow. Xtrata classifies all documents in the batch and passes the results to the next queue in the workflow. No registration is performed by Xtrata Server, which results in faster Xtrata Server processing. Quick Tour of the Xtrata Server User Interface Xtrata Server can be started from the Windows Start menu or from the Ascent Capture Batch Manager. If started from Batch Manager, Xtrata Server will process the selected batch and automatically shut down when processing is finished. If started from the Start menu, Xtrata Server will immediately begin polling for batches to process. If batches are ready for Xtrata Server, they are processed in order based on priority and age. Figure 5-1. Xtrata Server Getting Started with Ascent Xtrata 109

120 Chapter 5 During batch processing, various statistical and status progress information is displayed in the dialog window. Optionally, the processed images can be displayed with the zones as registered by Xtrata. The statistical information that is displayed is listed below: Current Batch Information Name of processed batch, the batch class assigned to this batch, and the batch type. Current Batch Progress Progress of the current batch per document, and the actions the Xtrata Server performs. Current Document Information Information on the currently processed document with the name of the current document class and the form type of the current document after successful classification. Current Document Confidence Information about classification and registration confidence of the current document in percent. If classification confidence is above the specified classification threshold, the form type is assigned to the image. Otherwise, it is left unclassified. If registration confidence is below the threshold, no registration will be performed for the form. Current Batch Statistics Information about classification statistics of the current batch. It displays the percentage of classified documents of the batch relative to all documents that have been processed and percentage of documents that could not be classified. Classified and unclassified documents always add up to 100%. The average confidence over all classified documents and the average difference of all classified documents can be used to judge overall classification quality. Current Document Display of the first page of the currently processed document. If a color document is processed, the color image is displayed. After classification and registration, the index zones are displayed at the correct position for online quality control. The display has no effect on performance since the image is loaded anyway. The document display can be hidden using the green arrow command button to the top left side of the image viewer. Event Log The event log frame displays Xtrata Server event messages. To see the full message you can double-click on an entry and the message is displayed in a message box. 110 Getting Started with Ascent Xtrata

121 Processing Batches Polling Interval As an unattended module, Xtrata Server requires no user intervention to process batches. Once started, it automatically checks (or polls) for batches to process. The polling interval is the amount of time (in seconds) between polling times. To set polling interval 1 From the Xtrata Server s menu bar, select Tools Polling Interval. The Polling Interval dialog box will display: Figure 5-2. Polling Interval 2 Select the desired polling interval. You can enter a value, or use the spinner controls. Valid values are from 1 to seconds. Single Step Mode There are two ways to process batches: Continuous mode: Xtrata Server processes the batches continuously and displays statistical results for the batch. Single step mode: To provide a way to see the results of Xtrata processing during runtime, the single step mode can be activated. The single step mode is accessible from the Tools menu or by pressing the F8 key. Xtrata Server stops after each processed document with a message box. The registration zones and classification results are displayed in the user interface, and can be examined. You can decide to proceed in single step mode, in continuous mode, or suspend the batch if you do not want to continue with the batch. To start Xtrata in Single Step mode 1 From Ascent Capture Batch Manager, select a batch that has the status Ready for Xtrata Server. 2 Start Xtrata Server by clicking the Process Batch button in Batch Manager s toolbar or by selecting Process from the context menu of the batch. The user Getting Started with Ascent Xtrata 111

122 Chapter 5 interface of Xtrata Server is displayed and the first document of the batch is processed. 3 Press the key F8 on your keyboard. After the current document is processed, Xtrata Server halts and a dialog is displayed. Figure 5-3. Single Step Mode To continue Xtrata in Single Step mode 1 In single step mode, a dialog is displayed after each processed document and document processing is halted. This allows you to see the classification and registration results for each document. The classification results are displayed in the Current Document Information Frame and in the Current Document Confidence Frame. The registration results are displayed in the Current Document Confidence Frame as registration confidence. If the Current Document Frame is opened so that the document is visible, the registered zones are displayed in the viewer and can be checked. 2 Click Step to process the next document ready for Xtrata Server and halt again. The dialog is displayed once more. 3 Click Continuous to switch to continuous mode to process the rest of the batch. By pressing key F8 again, you can switch back to step mode. 4 Click Suspend to exit processing and suspend the batch. Xtrata Server will go back to polling mode. Please be aware that the batch will be processed again from the suspended status if Xtrata Server has been started from operating system and is not stopped since the server will poll for the next available batch. Xtrata Server will be terminated if it has been started from batch manager. 112 Getting Started with Ascent Xtrata

123 Processing Batches Understanding the Log File Event messages are displayed in the event log frame and are saved to event log files. If the corresponding option in Menu Tools Logging Autoscroll is set, the event log will automatically scroll to the last entry only if the last entry has been selected. A selected entry is highlighted in blue. Double-clicking on a line opens the error message in a message box. Log files are created in Ascent Capture s Log folder. For each day, a new log file is created. Every time a new batch is opened by Xtrata Server, the program checks if a log file for the current day already exists. If not, a file is created. If Xtrata Server runs over midnight, the first batch that is opened after midnight causes the creation of a new log file. That keeps all log data for one batch together. Log file names include the current date as part of the file name: hor_log_<dateoftoday>.txt (e.g. hor_log_ txt) The structure of a typical log message displayed in the event log frame and stored in the log file is as follows: <Exact Time> [<Type>] <ID> <Message> The Type can be one of Info, Error, or Warning. The following is a sample log entry: 13:15:07 [Info] Xtrata Runtime Module started 12:12:30 [Info] Document 7 was classified with confidence 89,85% 12:12:30 [Info] Document 7 was registered with confidence 85,40% 12:12:30 [Info] Processing Document 8 13:52:09 [Error] Error in function "Register": No sample page found for Form Type "FT_ABC" The log file contains an information line for every page classified stating the classification result, confidence, and time. This information can be parsed by an external program (e.g. Microsoft Excel) to generate an overview of daily classification rates and confidences. Getting Started with Ascent Xtrata 113

124 Chapter Getting Started with Ascent Xtrata

125 Chapter 6 Correcting Classification Results Introduction Ascent Xtrata provides enhanced classification functionality to Ascent Capture, being able to classify up to 1,000 different form types in one batch class with high speed and accuracy. With Ascent Xtrata, it is easy to process mixed batches of different forms without needing to sort them into different batch classes. Ascent Xtrata is optimized for a very low error rate such that misclassification of images (assignment of an image to an incorrect form type) is minimized as much as possible. If classification cannot be done with the confidence threshold defined for the batch class, Xtrata Server will leave the document unclassified. A batch containing unclassified documents or any other errors, like document length or page sequence errors, is either routed to the Ascent Capture Quality Control module or to Recognition Server, depending on the error handling setting defined for the batch class. Batches that contain unclassified documents after processing in Recognition Server are rejected and routed to the Ascent Capture Quality Control module. For the manual classification of unclassified images, Xtrata Form Type Correction is provided as a custom panel in Quality Control. This user interface can be started from the context menu of a document from an Xtrata batch in Quality Control. This chapter introduces the Xtrata Form Type Correction panel and provides a quick tour of its interface. Getting Started with Ascent Xtrata 115

126 Chapter 6 Quick Tour of the User Interface Correction of classification results is a manual task that requires knowledge of the form types in the batch class. To help the user to perform this task, the Xtrata Form Type Correction panel displays the current image in the left pane and the first sample page of the selected form type in the right pane. The user needs only to compare the image against the sample pages in the display. In addition, the display also shows the classification confidence results of the first page to help the user quickly choose the correct form type. If a form type cannot be assigned, the unassigned images can be moved to a definition folder and used to define a new form type in Xtrata Forms Setup. This functionality is only available if Undefined Scanning is enabled as an Xtrata setting for the batch class. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for information about enabling undefined scanning for an Xtrata batch class. The Xtrata Form Type Correction panel is shown in Figure 6-1. The main interface items are described in the following sections. Figure 6-1. Xtrata Form Type Correction 116 Getting Started with Ascent Xtrata

127 Correcting Classification Results Toolbar The buttons on the toolbar allow you to navigate easily through the batch, display online help, and exit Xtrata Form Type Correction: Display First/Last Document Move to Definition Folder Display Online Help Exit Form Type Correction Display Next/Previous Unclassified Document Display Next/Previous Document Assign Form Type to Document Figure 6-2. Toolbar Buttons Note that the Move to Definition Folder button is only available when undefined scanning is enabled for the Xtrata batch class. Refer to Chapter 4 Using Xtrata Forms Setup on page 43 for information about enabling undefined scanning. List of Form Types The middle section shows a list of all form types defined for the batch class, with the classification confidence results for the current document. The list can be sorted by form type name or by confidence. By default, the list is sorted by confidence. In most cases, the correct form type is in the first three items in the list, making it easy to find and assign the correct form type even if the list contains several hundred entries. Image Viewers The two Xtrata Form Type Correction viewers show: The first page of the selected unassigned document (in the left pane) The first sample page of the selected form type (in the right pane) The viewers are synchronized for zoom and shift factors. For example, if you zoom in on the unassigned document, the same zoom factor is applied to the viewer with the sample page. Getting Started with Ascent Xtrata 117

128 Chapter 6 In addition to the images, the index zones defined for the currently selected form type are displayed. The overlap of index zones with existing structures on the displayed forms provides additional visual support for identifying the correct form type. Command Bar The region below the viewers and the list of form types contains command buttons and labels as shown below: Currently Assigned Form Type Next Form Type Display Online Help Assign Form Type Enable Quick Assign Close Xtrata Form Type Correction Figure 6-3. Command Bar Note that clicking Enable Quick Assign (the green lightning bolt) causes the buttons below the list of form types to change, as shown in Figure 6-4. With Quick Assign enabled, you can assign the selected form type and move to the next unassigned image with one click. Just click the Assign+Next button. With Quick Assign disabled, you must use two clicks to assign the selected form type and move to the next unassigned image. First click Assign to assign the form type, and then click Next.

Using Xtrata Form Type Correction Xtrata Form Type Correction is used to rapidly classify documents manually and at the same time watch the overall quality of Xtrata classification. The user interface is especially optimized for fast operation with a large number of form types. Starting Xtrata Form Type Correction You start Xtrata Form Type Correction from the context menu of any document in an Xtrata batch in Quality Control. 120 Getting Started with Ascent Xtrata

131 Correcting Classification Results To start Xtrata Form Type Correction 1 Start the Ascent Capture Quality Control module, and open an Xtrata batch. 2 In Quality Control, all documents are listed in the Batch Contents panel. Right-click a document in the list, and select Xtrata Form Type Correction from the context menu. The Xtrata Form Type Correction panel will open. Note For any Xtrata batch, you can open Xtrata Form Type Correction from the context menu of any document in the list. You do not need to select an unassigned document. Selecting Documents After Xtrata Form Type Correction has been started, the document that was selected in the Ascent Capture Quality Control module s list is displayed in the viewer in the left pane. The first sample page of the selected form type is displayed in the right pane. (See Figure 6-1.) To select a document in Xtrata Form Type Correction 1 Use the navigation tools in the toolbar to select a specific document. Open previous document without form type: Jump to the next document that is before the selected document in the batch and has no assigned form type. If the search gets to the beginning of the list without finding a document, it starts over from the end of the batch. If no document is found in the batch with an unassigned form type, the display is not changed. Open next document without form type: Jump to the next document that is after the selected document in the batch and has no assigned form type. If the search gets to the end of the batch, it starts over from the beginning of the batch. If no document is present in the batch with an unassigned form type, the display is not changed. First Document (F2): Display the first document in the batch whether it is classified or unclassified. Previous Document (F3): Display the document preceding the current document in batch order. If the current document is the first document in batch, then the last document in the batch is displayed. Next Document (F4): Display the document following the current document in batch order. If the current document is the last document in the batch, then the first document in the batch is displayed. Last Document (F5): Display the last document in the batch whether it is classified or unclassified. Getting Started with Ascent Xtrata 121

132 Chapter 6 Assigning Form Types Follow these steps to assign (or change) the form type of the selected document. To assign (or change) the form type of the selected document 1 Select the correct form type in the form types list. The first sample page of the form type is displayed in the right pane. The index zones of the sample page are displayed on the document. This allows you to quickly decide if the form type fits or not. 2 Assign the form type to the current document by one of the following actions: Double-click on the selected form type in the list. Press Enter. Use Assign selected form type to the document from the toolbar. Press the Assign button below the list. 3 Select the next document or the next document without a form type. 4 To combine steps 2 and 3, you can assign a form type and immediately jump to the next unassigned document. Enable the Assign+Next command button using the green arrow symbol below the form types list. Press Assign+Next to assign the selected form type to the current document and immediately jump to the next unassigned document. Moving Images to the Definition Folder If desired, you can move unassigned images from the batch to the definition folder, and then reuse the images to define new sample pages. For example, you can create definition batches from the images in the definition folder. Xtrata Server will send the results of processing the definition batches to Xtrata Forms Setup in the Administration module, allowing you to add the sample pages to batch classes. Refer to Definition Batches on page 46 for more information about definition batches. To move documents to the definition folder 1 From the Batch Contents panel in the Quality Control module, right-click a document for which no form type is assigned. Then, select Xtrata Form Type Correction from the context menu. 2 Use the Xtrata Form Type Correction panel to assign a form type. If possible, assign a form type. 3 If no form type exists for the document, click Move to Definition Folder. A message similar to the following will display: 122 Getting Started with Ascent Xtrata
