代码给出了数字图像处理图像复原运算方法中的自适应滤波、正则化滤波、盲去卷积滤波等滤波方法的实现过程，经matlab调试运行成功，效果明显(Code gives a computing method of digital image processing image restoration, adaptive filtering, regularization filter, blind go convolution filtering and other filtering methods to achieve process matlab debugging run successfully, the effect is obvious)

基于波前重构算法的sar雷达点目标成像实现，使用matlab实现(Wave-front reconstruction algorithm to achieve sar radar point target imaging)

this coding use for students who use matlab steganography. the code will be highly used in recent times.

说明：  有三种算法，分别是cmeans、fcm和som等对如iris和usps等数据的聚类。(There are three algorithms, cmeans, FCM and SOM to cluster data such as iris and USPS.)

robust segmentation for extra bright image

试用时域最小平方误差准则（最小平方逆设计）设计一个具有四项系数的IIR DF的系统函数，使其在y(n)=[3,2,1]输入激励下，输出v(n)逼近d(n)=[2,0.2,0.05]。令v(-1)=v(-2)=0。求出v(n)的前8个样值与d(n)进行比较。用matlab实现了此要求。(trial at the least square error domain guidelines (minimum inverse square design) design with a four DF IIR coefficient of the system function, so in y (n) = [3,2,1] incentive to import, export v (n) approximation d (n) = [2,0.2,0.05]. So v (1) = v (2) = 0. Get v (n) of eight samples value d (n) comparisons. Using Matlab realization of this request.)

本程序是QPSK信号在瑞利衰落信道下的仿真，已经过本人验证，适合初学者(This procedure is QPSK signal simulation in Rayleigh fading channel, I have been verified, suitable for beginners)
