| 摘 要： | 本文研究了一种基于图像置乱和小波变换的信息隐藏技术.该算法先将嵌入的水印信息置乱加密,然后嵌入到进行了离散小波变换的宿主灰度图像中.通过实验验证,该算法在对嵌入水印后的图像进行有损压缩、剪切、旋转、添加各种噪声等处理后,提取出的水印表现出了较好的鲁棒性.

| Abstract: | This paper discusses the digital watermark technology which is based on image scrambling and wavelet transform.After the scrambling and encryption of embedded watermark information,this algo- rithm embeds it into the host gray images with discrete wavelet transform.The experiment result showed that the algorithm has a good robustness for some image processing operations such as JPEG loss compression, cropping,rolling,blurring noise added and so on. |
