一种基于独立分量分析的数字水印算法

A New Watermarking Algorithm Based on Independent Component Analysis

提出一种基于独立分量分析的图像水印算法。该算法把一幅二值水印图像嵌入到原图像的小波逼近子图中,检测时利用快速独立分量分析方法来提取水印。实验结果表明,该算法加入的水印可以被恢复,并且具有一定的鲁棒性。

Proposes a digital image watermarking method based on ICA,the host image is transformed into discrete wavelet domain.A binary image is embedded to the approaching sub-image,a FastICA method is employed to extract the watermark.The experiments show that the algorithm has good robustness.
