Abstract :
Protecting images against illegal duplications is an important fact and recently many watermarking algorithms have been published. In this paper an enhanced SVD-based watermarking algorithm is proposed. In the proposed method U component is explored for embedding the watermark. Experimental results show that imperceptibility and robustness of the algorithm is good.
