一个计算多边形面积和周长的程序, 同时可以把多边形显示出来, 直观展现多边形形状.(A polygon area and perimeter calculation procedures, the polygons can be displayed simultaneously, intuitive show polygonal shape.)

用高斯混合模型进行数据聚类分析的matlab 程序。(Set of files for analysis of Gaussian mixture models for data set clustering etc.)

本代码为了检测哈弗曼编码后的图像压缩比，并且给出了哈夫曼的编码与解码(The code in order to detect Huffman encoded image compression ratio, and gives Huffman encoding and decoding)

说明：  对灰度图象进行正交变换,并进行滤波,产生平滑图象(Gray-scale images of the orthogonal transformation, and filtering to produce a smooth image)

matlab code for ultrasound image noise reduction

中值滤波，取出奇数个数据进行排序，用排序后的中值取代要处理的数据即可(median filtering.rar)

基于MDS-MAP和矩阵重复优化的无线传感器网络定位程序(Matrix based on MDS-MAP and repeat the optimization of wireless sensor network positioning procedure)

demo中基本上整理了目前常用的所有边缘检测算子，并添加了自定义的frei-chen、kirsch、direcedge、PrewittCompass、RobinsonCompass边缘检测算子function函数。此外，还有Ruzon罗盘算子的matlab实现程序，能对灰度图像的边缘加以检测。(demo, basically compiled all the commonly used edge detection operator, and add a custom frei-chen, kirsch, direcedge, PrewittCompass, RobinsonCompass edge detection operator function function. In addition, there Ruzon compass operator procedures matlab realize, can be gray-scale image edge detection.)
