Protecting images against illegal duplications is an important fact and recently many watermarking algorithms have been published to protect these images. In this paper two SVD-based watermarking algorithms are proposed and the results are compared with Chang’s method. In the proposed methods U component is explored for embedding the watermark. Experimental results show that imperceptibility and robustness of the algorithm is good.
