对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). a

数字水印嵌入算法，利用离散小波变换的（dwt）算法-Digital watermark embedding algorithm, using discrete wavelet transform (dwt) algorithm

该程序可以进行图像加密，运用了混沌和小波变换，希望对你有帮助。-adapt chaos and wavelet combined method of matlab image encryption

matlab数字水印加密和嵌入程序，含有小波变换和Arnold变换函数代码-Matlab digital watermarking encryption and embedding procedures, including wavelet transform and Arnold transform function code
