A code for pseudo coloring the images

说明：  The anisotropic diffusion filter is formulated as a process that enhances object boundaries by performing intra-region as opposed to inter-region smoothing

floyd算法 主要用于图论中的球最短距离的程序 可以直接求出任意两点间的最短距离(floyd algorithm used in graph theory the ball the shortest distance programs can be obtained the shortest distance between any two points)

九点差分格式，精度比五点差分要高，对于实现有限差分，是一个重要的程序(Nine-point difference scheme, the accuracy than the five-point difference is higher, for the realization of finite-difference, is an important procedure)
