Two enhanced SVD based watermarking algorithms using U matrix
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 comp...
