用matlab实现的图像加密算法-基于Arnold变换的图像加密-using Matlab achieve image encryption algorithm-based Arnold Transform Image Encryption

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
