| 摘 要： | 介绍了一种改进的基于小波包分解的自适应数字水印算法.该算法首先对水印图像作预处理置乱,然后对宿主图像进行3层小波包分解变换.在水印嵌入算法中,提出一种基于人类视觉特性(HVS)和小波包基的自适应水印嵌入算法.该算法引入人类视觉特性和基于小波包基的多分辨率嵌入技术,以达到更好的抗攻击鲁棒特性和视觉效果. |

| Abstract: | This paper presents a kind of improved algorithm of self-adaptive digital watermarking based on wavelet set decomposition.First,the algorithm pre-processes and makes the watermarking image into confusion,then it decomposes the host image into three layers with wavelet set transform.The authors present a kind of inlaid algorithm of self-adaptive digital watermarking based on Human Visual Sense(HVS) Property and Wavelet Set Group(WSG) in watermarking inlaid algorithm of the paper.The algorithm introduces HVS and multi-resolution ratio inlaid technique based on WSG so that better anti-offensive robustness property and visual sense effect are achieved. |
| Keywords: | image processing digital watermarking wavelet set decomposition transform copyright protection human visual sense property |
