| 摘 要： | 提出了一种基于小波零树结构的小波域盲水印算法,该算法能自适应地选取和修改小波的重要系数进行数字水印信息的嵌入,且具有较好的鲁棒性。该算法利用小波变换后的重要系数序列与给定序列之间的相关性来判断提取水印,提取时不需要原图像。结果表明,该算法是一种有效和可行的盲水印算法。

| Abstract: | This article proposes an image adaptive blind watermarking based on embedded zemtree wavelets. This algorithm can select and modify wavelet important coefficient adaptively in order to carry on digital watermark information inserting. It also has good robustness. This algofithm uses the correlation between the coefficient and the assigned sequence to judge and extract watermarking, the primitive image is not needed, and it is an effective blind algorithm. |

| Keywords: | blind watermarking correlation coefficient EZW(embedded zerotree wavelets) image adaptation |
