algorithms are language dependent ie characters and numbers should be in local language and if the language is changed, then the character identification algorithm will have to be changed each time the language changes This kind of problem has been targeted in the proposed work by using the statistical features of the text and can be fine-tuned easily just by replacing the statistical features data base of the particular language characters Though, it is observed that the vehicle is not only recognized by its number plate but the model of the motor vehicle also possesses many information so that it could be identified from the distance as the number plate can only be extracted once the camera is focussed on it But at the first sight, the vehicle is identified by it manifestation ie its shape, model, colour or style of the body Therefore, in order to identify a vehicle on road, prima facie, its data in terms of its body or appearance is an important source of information that must be retrieved or extracted from its image Keywords- Histogram of oriented gradients, Automatic Number Plate Recognition, binarizing I INTRODUCTION In the transport and traffic managing system, tracking or supervision of vehicles on road is very important Vehicles are identified with number plate and then from the record of the number plate contents the information is retrieve This way the system becomes complex and time consuming too The histogram of oriented gradients (HOG) is a feature descriptor used in computer vision and image processing for the purpose of object detection HOG counts occurrences in localized portions of an image Edge orientation histograms is similar to that of hog, but differs in that it is computed on a dense network of uniformly spaced cells and overlapping local contrast normalization is used to improve accuracy The vital role behind the histogram of oriented gradients descriptor is that local object appearance and shape within an image can be described by the distribution of intensity gradients or edge directions The image is segmented into small regions called cells, and for the pixels within each cell, a histogram of gradient directions is compiled For improved accuracy, the local histograms can be contrast-normalized by calculating a measure of the intensity across a larger region of the image, called a block, and then using this value to normalize all cells within the block This normalization results in better invariance to changes in illumination and shadowing The HOG descriptor has a few type of advantages over other descriptors Since it operates on local cells, it is invariant to arithmetic and photometric transformations Such changes would only appear in larger spatial regions The HOG descriptor is thus particularly suited for human detection in images II RELATED WORKS The paper introduces a machine learning system based on Artificial Neural Network for vehicle identification Haar filter is used for feature recognition of vehicles This system is merged with a Kalman filter, for multiple tracking of vehicles and thus damaged noisy signals are removed to construct an comprehensive vehicle identification and assessed on public province based images of vehicles on fluctuating traffic, clarification and climatic conditions Select samples and informative samples are retrained which provides high recalling rate, and give better localization effects on the recognized and trailed images This paper can be extended in the use of automated traffic control based on density of vehicles per unit time rather than fixed timings [1] This paper presents a recent template matching methods for detection and tracking of Vehicle Our focus is on systems where the camera is mounted on the vehicle and being fixed such as in traffic monitoring systems We discuss the general problem of on-road vehicle detection using template matching Also, discuss vehicle recognition through number plate and ways [2] In many countries around the world, Surveillance Cameras are used in enhancing the public security A traditional method in which stand alone cameras provide live feed and are still deployed at most of the places but the requirement of today s world is to add some intelligence to this systems Background Subtraction, segmentation, tracking and human behavior analysis are implemented to build such a system Lastly we talk about the future work which can lead to human behavior analysis like crowd counting, intrusion detection, loitering, crowd movement, vehicle tracking and all [3] A SVM classifier is used to extract the vehicle data for identification To acquire the vehicle image, histogram of gradients is used Further, the HoG are normalized with respect to size of the image/vehicle so that the HoG are not changed if the same image is giving zoom in or out effect Further, the HoG should not vary even if the image intensity is varied within the tolerance limits [4] This article presents an application of computer vision methods to traffic flow monitoring and road traffic analysis which utilizes image-processing and pattern recognition methods designed and constrains of road traffic analysis These methods combined together gives efficient capabilities of the system to monitor the road,, to measure the speed, to begin automated vehicle tracking, and also number plates of the car

traffic, it becomes difficult to identify vehicle owner who violates traffic rules and drives too fast which is the major problem in every country Therefore, it is not possible to grab the vehicle number from the moving vehicle because of the speed of the vehicle Therefore, Solutions to this problem is to develop Automatic Number Plate Recognition (ANPR) system Different methodologies are used but still there is a problem in some of the factors like high speed of vehicle, non-uniform vehicle number plate, characters of number plate and different lighting conditions can affect a lot in the overall detection rate In this paper, with parameters ie image size, success rate and processing time, different approaches of ANPR are discussed Towards the end of this paper, an addition to ANPR is suggested [6] This work is presented a real-time on-road vehicle tracking method which utilizes both shape and color information The follower builds statistical models of vehicle appearance for the target in color and shape feature spaces and continuously evaluates each of the feature spaces by using mean-shift algorithm The final position of the target is determined which are based on the similarity scores by fusing the possible locations found in different feature spaces together The planned method has been evaluated on real data, illustrating good performance [7] This paper developing a feature-based tracking system for detecting vehicles Instead of tracking entire vehicles, vehicle features are tracked to make the system strong to the problems of partial occlusion The system is fully functional under changing lighting conditions because the most important features at the given moment are tracked This paper describes the issues linked with feature based tracking, presents the realtime implementation of a sample system, and the performance of the system on a large data set[8] Automatic Vehicle Identification (AVI) has many applications in traffic systems (main road toll collection, red light disobedience enforcement, border and customs checkpoints, etc) License Plate Recognition is an effective form of AVI systems In this study, a smart and simple algorithm is presented for vehicle s license plate recognition system [9] This paper is presented a machine-vision system to detect vehicles running on red light or not follow the traffic rules The system operates during hours of daylight by getting video streams from two different sources One of them is a camera viewing the crossroads to identify unusual activity, while a second camera watches the semaphore to keep synchrony with the traffic controller During extended periods of time the system presentation and reliability have been tested on a real vehicular crossroads [10] Vehicle detection and tracking applications play a significant role in highway traffic surveillance control and urban traffic development In this paper, we present a brief overview of image processing methods and analysis tools which are used for vehicle tracking, counts, standard speed of each individual vehicle, traffic analysis that involved in rising traffic surveillance systems [11] The paper presents an approach for detecting vehicles in city traffic scenes by means of rule-based reasoning on visual data The strength of this is its formal separation between the lowlevel (used for extracting visual data under various lighting conditions) and the high-level module, which provides a general-purpose knowledge-based framework for tracking vehicles in the scene The synergy between the artificial intelligence techniques of the high-level and the low-level image analysis techniques provides the system with flexibility and robustness [12] License plate recognition (LPR) has greater efficiency for vehicle monitoring in automatic zone access control This Plate recognition system will keep away from special tags, since all vehicles have a unique registration number plate A number of techniques have been used for car plate characters recognition This system uses neural network character recognition and pattern matching of characters as two character recognition techniques In this approach multilayer feed- forward backpropagation algorithm is used The performance of the proposed algorithm has been tested on several car plates and provides very satisfactory results[13] This paper describes how to extract the vehicle license-plate and understanding of the registration code from a captured image in real-time The developed algorithm is divided into three stages: extraction of vehicle license plate from captured image, segmentation of license plate components and recognition of the license plate characters for from the registration code A control algorithm is also developed to choose between the recognition processes and rebuild the registration code from recognized characters [14] III ALGORITHM The objective of the proposed thesis work is to extract the vehicle information on road based on its appearance that is color, shape, model, any identifiable mark or any other source of information that is apparently available on the vehicle For, following objectives are summarised below: Image Acquisition of vehicles on road Segmentation of vehicle among different vehicles Image Enhancement and binarization Extraction of vehicle contour, size and other dimensional features Normalization of features with respect to zooming effect Vehicle data storage for its identification 31 Steps in Proposed Algorithm Step 1: Select Input of the original (RGB)
