K-means is a clustering algorithm In the beginning we determine number of cluster K and we assume the centroid or center of these clusters. We can take any random objects as the initial centroids or the first K objects in sequence can also serve as the initial centroids. There are two function for that the kMeanCluster and distMatrix

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：  有源滤波器检测算法的MATLAB程序，应用DQ0 算法，电流源加的是5 次谐波(active filter detection algorithm in MATLAB, application DQ0 algorithm increases the current source is the 5th harmonic)

Download the file town .jpg, which is a 1024×768, 256-grayscale image taken on a bright sunny day. The image was taken in the shadow of a building. As the result, the sunlight areas are glaring white and the shadow areas are dark and low contrast. Using the image enhancement techniques covered in class, increase the contrast and the brightness of the dark areas, and reduce the brightness of the sunny areas
