说明：  这两个小程序是matlab的.m文件，06为采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波，07采用matlab中的函数filter2对受噪声干扰的图像进行均值滤波。
(these two small procedure is Matlab. M documents, 06 for 2D median filtering function medfilt2 right by the Salt and Pepper image noise filtering, 07 using Matlab filter2 the function of noise interference by the image filtering.)
