本程序实现的是二维图形的限定Delaunay的三角剖分，算法的主要思想是采用微分方程数值解法中的有限元方法对二值图像进行三角剖分，程序为二维图像重建提供一个有利的基础。-this program is limited to the two-dimensional graphics Delaunay triangulation. The main idea of this algorithm is the numerical solution of differential equations b

结合matlab自带工具箱，进行二维轮廓网格划分，是有限元中比较好用的网格划分方法-Combining with matlab toolbox, two-dimensional contour grid, is more useful in finite element meshing method.
