| 摘 要： | 提出了一种基于奇异值分解的离散小波和离散余弦双重变换域数字图像水印算法。仿真结果表明，该算法不仅具有较好的水印不可见性，而且对常规攻击和几何攻击都具有较好的鲁棒性，且该算法采用灰度图像作为水印，增加了嵌入的信息量，在版权保护方面具有一定的应用价值。

| Abstract: | A digital image watermarking algorithm in dual transform domains of combination of Discrete Wavelet Transform (DWT) and Discrete Cosine Transform(DCT) based on Singular Value Decomposition(SVD) is proposed.The simulation results indicate that the algorithm has both good quality for watermarked image and excellent robustness against common attacks and geometric distortion,it uses a gray image as a watermark,increasing embedded information capacity,so it has some practical value for copyright protection. |
