| 摘 要： | 在分析打印与扫描过程的基础上，提出了一种基于嵌入式小波编码的数字水印算法。该算法利用小波的时频分析、多分辨分析以及对人眼视觉系统的自适应特性，通过对印刷图文进行特征提取，将水印信息自适应的加入到原始图文中。试验结果表明了算法的可行性和有效性。

| Abstract: | Based on the analysis of the process of printed and scanning,this paper proposes a kind of the digital watermarking algorithm rested on the embedded Discrete Wavelet Transform(DWT).This algorithm can attract the printing products using time and frequency analysis of wavelets,multi-resolution analysis,and self-adaptation features of Human Visual System(HVS),and embed watermarking infomation into the existing diqital images.The experiment results indicate that this algorithm is feasible and effective. |
