摘要
独立分量分析(ICA)是一种近期发展起来倍受关注的盲源分离算法。文章提出一种基于ICA的数字水印嵌入和提取算法。实验表明,该算法可以实现水印的盲分离,并且具有很好的鲁棒性。
Independent component analysis （ICA） is a novel approach of blind source separation that developed recently and received greater attention today. In this paper, an algorithm based on ICA technique for detection and extraction of digital image watermark is proposed. Experimental results indicate that this algorithm can realize the blind separation of digital image watermark and have good robustness.
