In Chapter 2, a detailed survey on digital image watermarking is presented. InChapter 3, an optimal scheme is proposed to use Human Visual System model tocompute masking function. It will be used to control the strength of watermark signalfor optimal embedding. In Chapter 4, we propose a novel watermarking scheme based on lattice vectorquantization. Some important transform coefficients of the original image are firstlymapped into the nearest neighboring lattice points by using lattice vector quantizer,then watermark signal is added to the lattice points.
