| Abstract: | In this paper, a weighted image watermarking algorithm based on human visual characteristics is proposed. The energy-distribution coefficients of the watermarking embedded into the image were properly designed to improve the transparency and stability of watermarks. The experimental result confirms the efficiency of the algorithm. |
