计算一幅图像的pnsr数值 只需要把要处理的图像直接输入就可以了 简单 方便(Calculation of numerical pnsr an image just to have to deal with the direct input of images can be a simple and convenient)

说明：  电子电路的重要材料 包括信号处理，模拟、数字电路等等(dianzi dianlu DSP，A/D,D/A)

四种聚类算法源代码及示例代码,本程序的最终目的是形成一套标准的用于聚类、可扩展的工具。包括的内容有1. 聚类算法：Kmeans和Kmedoid算法、FCMclust, GKclust, GGclust算法 2. 评估分类原型：程序可以在二维图像上绘制出聚类的结果 3. 验证：程序给每一个算法提供验证机制，每个聚类算法会统计(Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII)几种衡量指标。-Four kinds of clustering algorithms source code and sample code, the ultimate goal of this program is to form a set of standards for clustering, scalable tools. Including the contents of a. Clustering algorithm: Kmeans and Kmedoid algorithms, FCMclust, GKclust, GGclust algorithm 2. Assessment classified prototypes: programs can be plotted in two-dimensional image, the results of clustering 3. Verify: Program to provide an algorithm to each authentication mechanism, each clustering algorithm will calculate Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII) of several metrics.)

根据输入值的大小和输出值得大小，绘制相应的曲线，功率谱图(The size of the input and output values ​ ​ worthy size, draw the curve of the power spectrum)

用matlab实现支持向量机功能，可以进行四种核函数的选择，简单实用(support vector machine)
