| 摘 要： | 在图像中,ROI(region of interest)所指的是图像的感兴趣区域,也就是图像中对于观察者而言信息最为丰富的地方.因而对于感兴趣区域的水印嵌入一直是数字水印研究的重点和难点.本文以基于小波变化和奇异值分解的水印为基础的嵌入方法,在感兴趣区域嵌入鲁棒性水印,用于作为图像的版权认证,使得水印具有较强的鲁棒性和不可见性.

| Abstract: | In the image process,ROI means the region of interest in the image which has more details than other part in the image.It is very important and also very difficult to search the image watermark based on the ROI.In this paper,we provide a new way for watermark in the foundation of SVD and ROI,embedding robust watermark in the ROI for image authorize. |
