利用水平集函数来检测物体轮廓，一般水平集收敛用到signed distance function的，但是这里实现的程序不用每次都要进行reinitialization就可以使水平集函数趋于收敛。-The use of level set function to detect an object contour, the general level set signed distance function used in the convergence, but the program here

说明：此网格化函数为了避免进行网格点与实际采样点之间的距离运算以及判断， 通过将实际采样点的坐标映射到网格点坐标，网格点的坐标 和其在数据中的[i][j]有简单对应关系，可以由实际采样点 坐标简单得到其卷积范围内的网格点坐标-Descr iption: The function of this grid in order to avoid the grid points and the actual sampling point of the distance between

Theme: Object recognition using Geometric Properties(area, perimeter,circularity,etc) . In order to obtain the results the project was implemented using C++ and the tool C++Builder. For every geometric feature has been created a method that return a
