关于这个校正设计的程序，我原本打算做3个版本的。第一个就是现在传上来的这个。这个版本，提供了设计思路的由来和适当的过程的引导，但一些计算步骤由使用者自己来完成。我做这个版本的目的是希望，使用者能通过这个程序的使用明白校正的设计思路，至少是从我理解的程度上去理解。如果以后的师弟、师妹们能通过使用这个程序，更加轻松的掌握校正的方法。我就觉得我做了一件意义重大的贡献，我会感到自豪。所以也希望李老师能对其中的错误和不足进行指正。第二个版本是第一个版本的简化版，只给过程的引导，不给设计思路，主要是给用过第一个版本的同学一个加深联系的途径。(i don t know)

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 )
