Description: matlab数字水印程序m文件程序，用的是小波变换中的dwt方法，并且把小波变换分成了四个子带，选择的LL子带。svd算法与dwt相结合，加密方法是混沌加密。与我刚才上传的dwt_svd_GUI.rar是一个程序，一个是gui的，一个是m文件。-m digital watermarking matlab program documentation procedures, using a wavelet transform method in the dwt and the wavelet transform is divided into four sub-band, choose the LL sub-band. svd algorithm with a combination of dwt, encryption method is chaotic encryption. I have just uploaded a dwt_svd_GUI.rar procedures, one is the gui, one m file.
