| 摘 要： | 为提高水印的不可见性,提出1种基于水印信息压缩的图像小波域水印算法.通过细化处理和骨架缩放技术将水印图像浓缩,减少要加入的水印数据量.压缩后的水印被嵌入到图像三级小波分解后的低频逼近系统上,并通过逆过程进行水印提取,嵌入的水印具有较高的不可见性和较好稳健性.仿真实验证明算法具有很好的不可见性,经滤波、噪声、图像压缩和剪切等攻击后仍然能较好的提取水印. |

| Abstract: | To improve the imperceptibity of watermark,a image wavelet domain watermarking algorithm is proposed based on information compression.Through technologies of thinning image and skeleton scaling,the size of embedded data is reduced.The compressed watermarking is embedded into the loweast frequency subband after three levels wavelet decomposition of the image and can be extracted through a reverse process.The embedded watermarking has properties of high imperceptibility and good robust.Simulation experiment shows that the algorithm has good imperceptibility and the watermark can be well extracted for filtering attack,noise attack,image compression attack and cutting attack. |
| Keywords: | watermarking algorithm image wavelet domain information compression |
