F. chang Labeling algorithm(a treatise)

This is grass_fire Algorithm for object labeling

该算法可以完成二值图像的连通域标记， 并计算出各连通域的面积。非常的方便好用，本人已经测试。-The algorithm can complete the connected component labeling of binary images, and calculate the area of ​ ​ the connected domain. Very convenient and easy to use, I have tested.
