Image_enhancement

用music方法进行信源数估计的MATLAB程序，比较简单，用于雷达探测目标(Methods using music source number estimation MATLAB is relatively simple, for radar target detection)

In image processing, probably the most familiar is the image brightness and contrast adjustment

基于matlab小波分析人脸识别的特征提取(Extraction based on wavelet analysis matlab face recognition feature)

Algorithm Given are P training pairs {X1,d1,X2,d2....Xp,dp}, where Xi is (n*1) di is (n*1) No of Categories=R. i=1,2,...P Yi= Augmented input pattern( obtained by appending 1 to the input vector) i=1,2,…P In the following, k denotes the training step and p denotes the step counter within the training cycle Step 1: c>0 , Emin is chosen, Step 2: Weights are initialized at w at small values, w is (n+1)*1. Counters and error are initialized. k=1,p=1,E=0 Step 3: The training cycle begins here. Input is presented and output computed: Y=Yp, d=dp Oi=f(wtY) for i=1,2,….R Step 4: Weights are updated: wi=wi+1/2c(di-oi)Y for i=1,2,…..R. Step 5: Cycle error is computed: E=1/2(di-oi)2+E for i=1,2,…..R. Step 6: If p<P then p=p+1,k=k+1, and go to Step 3: Otherwise go to Step 7. Step 7: The training cycle is completed. For E=0,terminate the training session. Outputs weights and k. If E>0,then E=0 ,p=1, and enter the new training cycle by going to step 3.

svm 支持向量机代码 support vector machine(support vector machine svm)

通过matlab工具箱，较为巧妙地将数据导入，并形成了多点之间的距离等数据和比较美观的图示。(Matlab toolbox more skillfully data import, and the distance between the multi-point data and more beautiful icon.)

本程序通过优化ICA算法实现了混合图像的盲源分离，分离效果优于一般ICA算法(This procedure optimized ICA algorithm is a mixed picture of blind source separation, separation is better than the general ICA algorithm is)
