图像的中值滤波和邻域滤波。基于matlab仿真通过，内附图片和仿真结果。-Image of the median filter and the filter neighborhood. Matlab-based simulation is passed, containing pictures and simulation results.

使用了L形邻域进行纹理生成，是很初步的程序，用于灰度图像，而且还未考虑边界的情况，仅供参考-Use the L-shaped neighborhood texture generation, is a preliminary program for gray image, not to consider the boundary conditions for reference only
