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.

• 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。
