一种鲁棒性好的水印算法

水印技术作为信息隐藏和版权维护的一种有效手段，发展得相当迅速。但是很多水印系统都有一定缺陷，如对透明性和鲁棒性的折中关系难以掌握平衡；不能使用标志符作为水印信息。该文将就上述问题作了一些改进。提出了一种鲁棒性好的、防剪切的数字图像水印算法。算法采用有意义的标志符为水印，考虑HVS特性，并具有水印自适应调节特性，检测结果表明，该算法具有较强的透明性和鲁棒性，且计算量少。

A Good Robust Image Watermarking Algorithm

AS an efficient way of information hiding, digital watermark has bee n made great progress. But many digital watermarking architectures are low effic iency. This paper provides a new architecture that is robust and invisible. Base d on human visual system(HVS), the architecture is adaptive, visible and robust. It can avoid clipping. Moreover, the compute process of the architecture is eas y.
