摘要

提出了一种基于水平集方法的多比特顽健水印算法。该算法首先利用水平集方法在图像中确定一个稳定的图像轮廓

进而确定一个位置稳定的单位圆

然后计算这个单位圆的伪Zernike矩

利用抖动量化的方法将水印嵌入伪Zernike矩的幅值上。水印的检测过程采用均方根误差法提取出水印。克服了传统基于伪Zernike矩水印算法的缺点

同时可以很好地抵抗各种几何攻击。

Abstract

A multibit watermarking algorithm based on level set method was proposed.First

the stable location of the unit disk was found using level set method.Then

pseudo-Zernike moments were calculated.At last

the watermark was embedded by modifying the pseudo-Zernike moments.In the extraction process

the root-mean-square-error method was employed to detect the watermark.Simulation results show that the algorithm overcomes the defect of the traditional al-gorithm based on pseudo-Zernike moments

while be robust against geometric attacks.
