二维离散小波变换，实现一幅图的分解与重构。恢复原图-Two-dimensional discrete wavelet transform, the realization of a diagram of the decomposition and reconstruction. To restore image

图像的多尺度离散小波分解示例程序，这个程序用的是matlab自带的图片，因此可以轻松自由运行-Multiscale image discrete wavelet decomposition of sample procedures, which is used matlab own pictures, so can easily free-running

decomposition image

根据对所输入的png格式的真彩图像、小波类型（db9或haar）和相应的阈值进行了三级非标准小波harr或db9的分解和重构，从而达到了对原图像的压缩处理的 -Entered based on the true color of the png format images, wavelet type (db9 or haar) and the corresponding threshold for the three non-standard or harr wavelet decompos

PHT矩分解。用于音频或者图像数据的极谐波变换，使音频数据在受攻击后仍能够较好的提取水印-PHT matrix decomposition.Audio frequency or image data of Fourier transform, the audio data in attack can still good after extracting the watermark
