(ROI) coding demand more efficient and versatile image

In this paper, we start by first characterizing the most important and distinguishing features of wavelet-based watermarking schemes. We studied the overwhelming amount of algorithms proposed in the literature. Application scenario, copyright protection is considered and building on the experience that was gained, implemented two distinguishing watermarking schemes. Detailed comparison and obtained results are presented and discussed. We concluded that Joo’s [1] technique is more robust for standard noise attacks than Dote’s [2] technique. Keywords—Digital image, Copyright protection, Watermarking, Wavelet transform.
