Genetic watermarking based on transform-domain techniques

An innovative watermarking scheme based on genetic algorithms (GA) in the transform domain is proposed. It is robust against watermarking attacks, which are commonly employed in the literature. In addition, the watermarked image quality is also considered. In this paper, we employ GA for optimizing both the fundamentally con4icting requirements. Watermarking with GA is easy for implementation. We also examine the e6ectiveness of our scheme by checking the 7tness function in GA, which includes both factors related to robustness and invisibility. Simulation results also show both the robustness under attacks, and the improvement in watermarked image quality with GA. ? 2003 Pattern Recognition Society. Published by Elsevier Ltd.
