| 摘 要： | 数字水印技术是实现数字产品版权保护的一种新方法。本文提出了一种基于人类视觉系统(HVS)和图像统计特征的数字水印方法，该方法将水印作为一幅二值图像来处理，并根据JND值将小波系数分为两类，对不同的类采用不同的嵌入对策。实验结果表明水印是不可感知的，并且对于各种图像处理操作是鲁棒的。

| Abstract: | Digital watermarking technique is a new method for copyright protection of digital products.In this paper,an algorithm using human visual system(HVS)and statistical characteristic of image is proposed.The method processes the watermark as a binary image and classifies the wavelet coefficients into two groups using JND.The watermark is embedded in different way respective to the class.Experimental results have shown that the watermark is invisible to human eyes and robust to various image processing operations. |
