| 摘 要： | 数字水印技术是实现数字产品产权保护的一种新方法。本文提出了一种基于HVS和自适应小波变换的彩色图像水印改进算法。首先利用改进的自适应小波变换对原始图像进行处理,然后采用混合置乱算法对水印图像进行处理。同时根据HVS的特点来确定水印的嵌入强度。实验证明这种算法具有较好的隐蔽性,对各种图像处理操作是鲁棒的。

| Abstract: | Digital watermarking technique is a new method of protecting property right of digital production.In this paper,an improved watermarking algorithm for color image based on human vision system(HVS) and adaptive wavelet transformation is proposed.First,adaptive wavelet transformation is acted on original image,and then mixed scrambling algorithm is adapted to treat with the watermarking image.According to the HVS's characteristic,the watermarking embedding intensity is determined at the same time.The experiment results prove that the algorithm presented here has a better concealment and robust effect on all kinds of image processing. |
