毕设时的语音符号处理源程序

Retinex算法是最实用的图像处理方法以突出边界，提高对比为目的。这是最简洁的retinex实现。(Retinex provides the closest to eye perception algorithm to process the images.)

This Matlab script solves a particular case of the parabolic PDE studied in class using the CrankNicolson finite difference algorithm.

This book talk about how to beginn with Rtutor program.

小波不同于传统的傅里叶变换和短时傅里叶变换，它具有随信号频率变化的时间频率分析能力，因此可以用来去噪！(This program implement the function of the interference of the noise！)

说明：  原理：以待处理的像素作为中心，取一个nXn的模板，在模板中选择k个与待处理像素的值最接近的像素，将这k个像素的均值替换原来的像素值。 假设n=3，k=5，调用方法：b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))
