| Abstract: | An algorithm based on discrete wavelet transformation embedding digital watermark into image is analyzed.Using the human visual system(HVS),the difference between original image and watermarked image could hardly be recognized by human sight,and the security of watermark is improved.Meanwhile,inserting digital watermark into the most important part of the wavelet transformation coefficients can improve the robustness of the watermark.The experimental results show that the algorithm is of less complexity,mor... |
