摘要： 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?

Abstract: 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.
