摘要
基于自相似分形集抗几何失真的特性 ,提出了一种首先将数字水印信息转化为生成自相似分形集的IFS系数 ,然后将由该IFS生成的自相似分形图嵌入到图像中去的数字水印算法 .
Based on the strongly robust character against geometric distortion of self similar fractal, a new algorithm for digital watermarking is put forward. The digital watermark is first transformed into coefficients of an IFS, and the self similar fractal image created by this IFS is embedded into the given image. It is tested that this algorithm is robust against geometric distortion and JPEG.
