Abstract

In this paper a new watermarking scheme is proposed which combines Singular Value Decomposition (SVD) and its multiresolution form (MR-SVD).The experimental results obtained through the proposed scheme establish the fact that the scheme yields better PSNR value thereby providing good imperceptible and robustness against various attacks. Both MRSVD and SVD are based on matrix operation, so their combination avoids the convolution function (as in the case of DWT) which involves a lot of resources.
