| 摘 要： | FastICA工具可以用于直接叠加或提取的图像水印方案，文章采用了定量分析法选取嵌入矩阵，对水印嵌入不可见性有很大提高，PSNR达到68．55dB，且具有很好的鲁棒性。该图像水印算法进一步提出Inv（A）使提取算法用于直接叠加或提取的图像水印方案中，不仅成功解决了FastICA用于直接叠加或提取图像方案提取水印的两种不确定性问题，而且在一定程度上增强了鲁棒性。

| Abstract: | Using the FastICA tool to direct superposition/extraction image watermarking scheme, the paper determined the embedding matrix by quantitative analysis, so that the algorithm shows good robustness and the visibility of the extracted watermark is good. The image watermarking scheme which further put forward the direct inversion algorithm for direct superposition / extraction , not only solved the two kinds of uncertainty in the first scheme to extract watermark, but also enhanced the robustness in some degree. |
