找出图形图像的面积，显示通过变化后的图像，用c++与OPenCV共同实现。-To identify the area of graphic image to show through changes in image, using c++ and realize common OPenCV.

迷宫算法遍历二值图像区域，获取面积并输出，稍加修改可以得到区域面积，重心等信息-Maze traversal algorithm for binary image region, access to the area and output, can be slightly modified area, the focus of information
