Description: 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。-on Contourlet Transform algorithms. And wavelet transform is different Contour let transformation similar to that segment (the base contoursegment be a multiresolution, Local, Image directional said. Watermark signal through content-based program by loading Contourlet Transform- few. Platform: |
