这是一篇利用非线性扩散方程进行去噪的文章，在文章中说明了如何在去噪和保持边缘间达到一个较好的平衡。-This is a nonlinear diffusion equation denoising article The article explains how the denoising and maintain an edge among achieve a better balance.

这是在计算微分方程时遇到扩散系数时的程序，很有效。-This is the calculation of partial differential equations encountered discrete diffusion coefficient of procedures, very effective.
