小波降噪程序，可对信号进行heursure阈值消噪处理。,Wavelet Denoising procedures can signal heursure threshold de-noising processing.

用MATLAB对一图象分别用不同小波分解，观察高低频部分进行重构，比较重构误差，再进行阈值消噪，比较消噪前后图象。-MATLAB noiswom

基于MATLAB语言，分别用不同小波对一图象分解，观察高低频部分进行重构，比较重构误差，再进行阈值消 噪，比较消噪前后图象。-Based on MATLAB language, respectively, with different wavelet decomposition of an image, observe high frequency part of the reconstruction, comparative reconstruction error, then the thr
