摘要
鲁棒数字图像水印已经成为因特网迅速发展时必须提供的版权保护利器,但是,当前流行的鲁棒数字图像水印算法在水印的不可感知性上离真正的满意程度距离较远,往往是与原图有较明显的区别,并未完全达到优秀水印的要求。在介绍当前流行的鲁棒算法后,重点介绍了一种最新的基于人眼视觉模型,即基于NVF的鲁棒数字图像水印算法,并对该算法与流行的算法进行了不可感知性上的仿真对比。实验结果表明基于NVF的算法在版权水印隐藏的不可感知性上达到了令人满意的效果。
Robust digital image watermarking has become an effective protective tool of copyright in the Internet. But nowadays,popular robust digital image watermarking algorithms cannot perform so perfect when it comes to the invisibility of watermarking. This paper introduces you all these algorithms and focus on a newly forwarded robust digital image watermarking algorithm, which was based on human visual system, using NVF. And we simulate this algorithm and the most popular algorithm DCT. The Contrast shows that the algorithm using NVF reaches the satisfaction of human visual system.
