buck pid仿真 BUCK 的 PID 控制，调整参数，更深入理解 PID 控制 学习使用 MATLAB ，并在 MATLAB 中建立电力电子仿真电路模型(buck pid)

在matlab软件中，自己编程实现的一个分类算法，算法首先采用kmeans与fcm聚类分析方法进行采样，然后利用svm对选取得样本进行分类(In matlab software, own programming to achieve a classification algorithm, the algorithm first used fcm kmeans cluster analysis methods and sampling, and then use the elections to obtain samples for svm classification)

Coding for image retri

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)

This is a two stage method in which at first image RGB compensated and then converted to YCbCr to normalise overall illumination of image.Its cascaded implementation of section 2.A of paper "A FAST SKIN REGION DETECTOR" by Phil Chen, Dr.Christos Greecos, ESC Division Research 2005,and section 2.1 of paper "Simple and Accurate Color Face Detection Algorithm in Complex Background" by YUI TING PAI et al. ICME 2006 . Please go through those papers for more details.
