该文件为二维网格划分程序，网格划分是数值模拟软件的前处理部分，他决定了数值模拟过程的时间和计算结果的精度-the document for the two-dimensional mesh procedure, the mesh is the numerical simulation software before processing. He decided a numerical simulation of the time and the precision of the results

Delaunay网格一次性生成，能正确的处理大型的顶点数据-Delaunay triangulation

基于matlab的简单人脸识别，这里通过对人脸图像打上网格，对区域块图像做二值分析，通过像素比例来做处理。进而得到人脸区域。-A simple matlab based face recognition, the face image of a grid, the two value image through the analysis of the regional block, the proportion of pixels to process. To get the face reg
