Vision for Interactivity: By Priyanka Sharma To build a Watermarking Model Using MATLAB. There is an increasing need of software so a battle begins between in order to provide copyright protection for intellectual property that's in digital format. For instance,the widely used DCT coefficients used in the JPEG and MPEG-2 standards. In fact when working on the DCT coefficients domain one may take advantage of the relative independence between the maximum allowable perturbations at every coefficients. Это и многое другое вы найдете в книге New Fragile and Non Blind Watermarking Insertion Model using MATLAB (Priyanka Sharma)
