FFT可以将一个信号的频谱 提取出来，这在频谱分析方面也是经常用的。 (A signal can be extracted from the FFT spectrum, which spectrum analysis is also often used.FFT)

this file describes and run the using WAVELET on a picture.

几个MATLAB实现的GUI界面，如多选菜单，可控制小球运动速度的用户界面，函数变换等主要共初学者参考使用！(several MATLAB GUI interface, such as more election menu control the ball movement speed of the user interface, the main function transform a total beginners reference!)

本书是讲用matlab工具箱处理小波分析算法的书籍，书里包含了工具箱的所有常用函数。(This book is about dealing with wavelet analysis toolbox matlab books, the book contains all the common functions of the toolbox.)

说明：  图像压缩，主成分分析的应用介绍，很有用啊(Image compression, principal component analysis applications introduced useful)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
