| 摘 要： | 本文提出了一种基于分块迭代函数系(PIFS)的小波域水印算法。通过PIFS变换将水印图变换为自相似分形水印图,然后用小波变换进行水印的嵌入、提取。实验证明该算法有良好的鲁棒性,同时保证了水印的不可见性。 |

| Abstract: | A digital DWT watermarking algorithm based on PIFS is presented in the paper.Through the PIFS,we transform it to a since similar fractal image,and then use DWT to embedded and extract the watermark. Experimental evidenced that this algorithm have good robust,and guarantee its invisibility. |
