| 摘 要： | 提出了一种基于小波域和独立分量分析的盲分离数字水印算法.该算法将水印置乱并乘以相应的系数,将此信息嵌入到经过二级小波变换的原始图像的逼近子图中,提取时利用快速独立分量分析实现了原始图像和水印的盲分离.经过大量实验证明,重构后得到的水印图像具有良好的不可见性,对叠加了水印的图像经过多种干扰及信号处理后,能够有效地检测出水印的存在.

| Abstract: | A blind separation algorithm based on ICA and wavelet domain is proposed. First, scrambled watermark signal multiplied ap- propriate coefficient, then it is embedded in 2 level wavelet approximation of original. By using FAST ICA watermark is separated from the watermarked image without original. A great deal experiments demonstrate recomposed image has better imperceptibility and watermark could also be effectively detected even thought watermarked image signal is attacked by some strong interference and s... |
