摘要
本文提出了一种基于快速独立分量分析的图像水印算法。该方法是把一幅二值水印图像嵌入到原图像的小波逼近子图中 ,检测时利用一种FICA(快速独立分量分析 )方法来提取水印。实验证明 ,该水印具有较好的透明性和较好的鲁棒性。
The paper proposes a digital image watermarking method based on FastICA (Fast Independent Component Analysis).In this method, the host image is transformed into discrete wavelet domain. A binary image is embedded to the approaching sub image. When extracting the watermark, a FastICA method is employed. The experiments show that the algorithm has good transparency and robustness.
