| 摘 要： | 数字水印是现在多媒体信号处理研究的一个热点,已经有许多关于数字水印嵌入和提取的方法.增强数字水印的鲁棒性是数字水印问题的关键.本文将独立分量分析用于数字水印,即把承载图像和水印图像在空间域直接混叠,并利用独立分量分析(ICA)的方法提取数字水印,得到了很好的结果.计算机实验结果表明这是一种鲁棒性极强的新方法.

| Abstract: | The research on digital watermark is a focus of multimedia signal's processing. So far, there have been many methods to embed and extract watermark. What is important to digital watermark is how to improve its robustness. In this paper,the independent component analysis (ICA) is used in our watermark scheme, that is, we mix the host image and the watermark directly in spatial domain and then use ICA to extract the watermark. We get excellent simulated results.Hie simulated results show that it is a new method with very outstanding robustness. |
