用matlab实现的中心加权滤波函数，中心权重为3，滤波窗口为3*3，参数可自行修改，可进一步改成可变参数函数。cwm_test为测试程序。(Weighted with matlab filter function to achieve the center, the center weight of 3, 3* 3 filter window, parameters can modify, change the variable argument function further.)

this is my code which i learnt in image processing lesson. it finds any geometric shape and draw black lines around it which stands on a white background. it could help how to find a shape for new learners in DIP

使用matlab中仿真实现差分进化算法，可在多目标优化的应用的使用(matlab differential evolution (DE) algorith)

information.m用来计算两个一维向量x和y的互信息。把压缩包中两个程序放在一起就可以运行(information.m used to calculate the two one-dimensional vectors x and y of the mutual information. The compressed package of two programs can run together)

说明：  介始了图像增强的主要技术，特别是图像直方图、频率域滤波、彩色图像分解处理技术，有matlab代码。(Medium before the main image enhancement technology, especially the image histogram, frequency domain filtering, color image decomposition process technology, a matlab code.)

一个描述奇异值分解的matlab小程序，通俗易懂，方便移植。(A description of the singular value decomposition matlab small program, easy to understand, easy to transplant.)
