数字图像处理，非线性平滑滤波器的matlab源代码，N为模板大小(正奇数)-digital image processing, nonlinear smoothing filter Matlab source code, N as a template size (is odd)

这是一个基于偏微分方程的图像处理问题的非线性平滑滤波器的程序!-This is a partial differential equations based on the question of image processing procedures for non-linear smoothing filters!

对图像进行算数平均滤波，希望对大家能有所帮助。-The image, and I hope to average filtering arithmetic we can help.
