matlabf非常好基于Contourlet变换的水印算法.与小波变换不同的是Contourlet变换采用类似于线段（contoursegment的基得到一种多分辨、局部化、方向性的图像表示。水印信号通过基于内容的乘性方案加载到Contourlet 变换系数-matlabf very good Contourlet Transform-based watermarking algorithm. and wavelet transform is different Contourlet trans

CT based encryption 1. Open contourlet 5 and run aaa.m for image decomposition and for denoising 2. Open tsss and A_hidetext.m and set break point at line 109 and run 3. After selecting image ind text press F5 4. Now run H_finalextra

这是国外最新的医学图像的数字水印，contourlet变换，不错的学校资料，本人在学习中-This is the latest foreign medical image digital watermarking, contourlet transform, a good school information I learn ...

关于半脆弱水印的几篇文章，其中包括小波变换的应用以及contourlet变换的应用等，涉及领域为半脆弱数字图像水印已经篡改检测。-Semi-fragile watermarking of several articles, including the application of wavelet transform and Contourlet transform application areas for semi-fragile digital image watermarking has
