采用混沌和小波相结合的方式实现的图像加密matlab程序-Using chaos and wavelet methods to achieve a combination of image encryption matlab program

采用小波变化来完成数字水印的加密和解密，并且加入了猫脸变换-Wavelet change digital the watermark encryption and decryption, and cat face transform.

matlab小波工具箱应用 多尺度小波变换 提取细节 压缩数据，对数据加时间窗，以50个数据为窗求小波细节然后取绝对平均得到一个数据-matlab wavelet toolbox application of multi-scale wavelet transform to extract details of the compressed data, the time window for data encryption, data window to 50 and then take the
