说明：  均值滤波对高斯噪声的影响，均值滤波是经典滤波算法，用于图像处理领域，本代码用matlab开发。(Mean Gaussian noise filter, mean filter is a classical filtering algorithm for image processing, the code developed using matlab.)

matlab的m文件 计算两幅影像的协方差 源码简洁高效(matlab m-file， computing the covariance of two images， simple and efficient source)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

说明：  matlab基础知识，PPT文件，内部资料简单，对于深入学习的人不是很合适(matlab basic knowledge, PPT files, internal information is simple, the depth of learning are not very suitable)
