八邻域实现的连通域标记，可以去除小的区域-Achieve eight neighborhood connected component labeling, you can remove some of the small non-candidate region

运用matlab编码标记连同区域,使得相同的部分进行连接，可用于图像的拼接(using matlab to connect the area)

采用连通区域算法，实现目标区域的连通标记，有利于目标的分割(The connected domain algorithm, to achieve connectivity marking the target region, is conducive to the target segmentation)
