A Novel Watermarking using Multiresolution SVD

the daily advancement of technology, copyright protection of all types of digital media has become an important issue. Thus to aid the copyright protection digital watermarking has emerged as solution to this problem. In this paper a new digital image watermarking scheme is proposed which combines Singular Value Decomposition (SVD) and its multiresolution variant. Tests have been undergone to check the proposed scheme for robustness and imperceptibility. The scheme has been compared with 3 previously standard schemes with respect to normalized correlation coefficient value of detected watermark.
