5 xi LIST OF FIGURES FIGURE NO TITLE PAGE 1.1 The detailed scope of the project The general branches of data embedding area General framework of data embedding General framework of data embedding The model of image watermarking in communication theory The classical model of communication system Watermark Embedding Scheme Watermark Extraction Scheme The three requirements of watermarking, in which a trade-off should be made between them The algorithm of embedding a watermark using Bit Plane Mapping method Example on histogram shifting, where the zero point is 255, and peak point is Bringing an image into DCT domain The logistic bifurcation diagram Proposed methodology Embedding process using HS watermarking method Extraction process using HS watermarking method Embedding Process Algorithm for the Extracting Process The set of testing images. 48

6 xii 5.2 Embedding capacity in HSW at T=0, 10, 100 and 1000 respectively Refer to the amount of payload enter inside the host image and equal to 1130 bits for the threshold equal Comparison between original and watermarked image of Baboon. Watermark is achieved using HSW at T= Show the extract for the payload with same data entered in the embed process (a) Show the original image. (b) Show the proposed luminance masking used in the embedding stage to enhance the visual quality of the output image Logistics map to generate sequence 2d of the watermark Show (a) is the original image and (b) is the watermarked image with incorporate the luminance masking, PSNR is 37.5(db) Show the watermark to be inserted in the host image Watermark extract Show comparative between proposed Spread Spectrum in term of enhance the visual quality measured by PSNR (db) with (classic Spread Spectrum, proposed Histogram Shifting, Bit Plane Mapping). 63
