这是基于matlab的图像去噪程序，使用小波包的方法实现。默认阈值。及小波分解重构等。-This is based on Matlab image denoising, the use of wavelet packet method. The default threshold. Wavelet decomposition and reconstruction, and so on.

利用matlab自带的小波函数对音频进行分解然后嵌入经降维之后的图像水印并提取-Matlab comes with wavelet function to decompose the audio and image watermark embedded by the dimensionality reduction and extract
