| 摘 要： | 提出了一种基于DCT的鲁棒性水印新算法，即利用人类视觉系统的掩蔽特性，通过调整非平滑区图像块的两个中频DCT系数的大小来加入水印信息。实验结果表明，该算法具有较好的隐蔽性，对常规攻击具有较好的鲁棒性。

| Abstract: | This paper proposes a new watermarking algorithm for good robustness based on DCT domains, i.e. by using the masking characteristics of human vision system, the algorithm adjusts two coefficients of the middle frequency of the blocks which are not the smooth areas to embed the binary watermarking. The result shows that the algorithm enjoys good invisibility, meanwhile, it has good robustness towards routine attacks. |
