本程序作用是首先载入图像信号,使用小波变换,比较显示不同阈值下的重构图像及相关信息，即小波变换在不同阈值下重构的测试演示程序 -This role is to first load the program image signal, using wavelet transform, comparison shows that different thresholds of the reconstructed image and related information, that is a dif

原始txt信号载入，小波变换，小波2、3层低、高频系数重构(The signal is loaded, the signal is intercepted, the signal is transformed by wavelet transform, and the wavelet is reconstructed with low and high frequency)

小波变换，小波重构，MATLAB，数据载入，绘图(Wavelet transform, wavelet reconstruction, MATLAB)

小波变换，小波重构，信号载入并绘图，含信号数据，MATLAB(Wavelet transform, wavelet reconstruction, signal loading and plotting, including signal data, MATLAB)
