Copyright protection of color images using a novel wavelet based watermarking algorithm

The field of digital watermarking being one of the important areas of research has received a lot of attention from researchers over last two decades, and a number of techniques have been developed. In this paper novel watermarking scheme for copyright protection of color images using wavelets is presented. The results obtained have clearly shown that the scheme is resilient to various attacks such as image compression, noise besides rotation, scaling and transformation.
