| Abstract: | In order to improve the robustness of digital watermarking for copyright protection, a novel position and method complementary embedding algorithm is proposed, which is based on the analysis of the unbalanced characteristics for different image processing methods. The wavelet coefficients are selected by Human Visual System (HVS) to ensure the transparence of watermarking. Experiment results demonstrate that this algorithm can resist diversified image attacks, and has good robustness. |
