| 摘 要： | 针对目前水印信息表达的含义不是很丰富的缺点，提出一种把灰度图像作为水印的算法。先进行水印预处理一灰度水印在位平面分解，之后再分别嵌入在二维小波变换图像的各个频率系数中。实验结果表明，该水印算法除具有较丰富的信息外，而且水印安全性高、不可见性好，鲁棒性较强。

| Abstract: | Aiming at current problems of lack of watermark information expression,propose an algorithm,which takes gray image as its watermark.Gray image watermark will be embedded into each frequency coefficient of two-dimensional wavelet transformation image after decomposing in the bit plane.In addition to rich information,the experimental results show that the watermark algorithm proposed has good advantages such as high security,sound invisibility and strong robustness. |
