基于susan、hirrs方法的角点检测程序、采用matlab编程，易于阅读。(Corner Detectio)

这是一个计算近似熵的程序，后续开发可以通过控制维度m调节搜索最佳评价维度。(This is a program to calculate approximate entropy.you can control dimension to search the best uation dimensions for deeper study.)

说明：  基于MATLAB的程序..利用蚂蚁算法求解TSP问题 (MATLAB-based procedures .. use ant algorithm to solve TSP problems)

- K means algorithm is performed with different initial centroids in order to get the best clustering. - The total cost is calculated by summing the distance of each point to its cluster centre and then summing over all the clusters.Based on the minimum overall cost achieved during each iteration of iterKMeans the pixel assignment to their respective clusters are made and final compressed image is obtained. This algorithm will run slower as the number of clusters , size of the image and number of iterations increase.

说明：  画渗透率曲线 根据已知网格和数据，画等值线。(Permeability curves have been drawn based on HowNet and the data grid, contour drawing.)
