matlab对图像随机添加四种噪声，然后分别通过自编中值滤波，均值滤波，高斯滤波，和维纳滤波进行滤波(matlab add four random noise to the image, and then were filtered by self median filtering, mean filtering, Gaussian filtering, and Wiener filtering)

说明：  图像二值化，边缘提取包含sobel、log、canny等方法，还有图像直方图均衡化，对比度增强等(Image binarization, edge extraction includes sobel, log, canny and other methods, as well as image histogram equalization, contrast enhancement and so on.)

使用K－均值聚类算法在IRIS数据上进行聚类分析.(K-means clustering algorithm using IRIS data in the cluster analysis.)

说明：  _余松煜数字图像处理，非常好的一本书~非常有用(_ Song-Yu Yu digital image processing, a very good book ~ very useful)

利用matlab求响应程序，可以求出系统的响应 (use this project can sovle the problem )
