说明：  ：在线标记和区域增长的基础上提出了一种二值图像连通区域标记的快速算法。该算法 综合了线标记法和区域增长法的优点，对图像进行一次扫描就可以标记所有连通区域，避免了重复标记问题；同时该算法不受标记的区域形状影响，具有良好的鲁棒性
(: On-line marking and regional growth based on a binary image connected region of the fast algorithm for marking. The algorithm combines the tag line and the benefits of regional growth method, a scanned image can be marked on all the connected region to avoid the problem of duplicate tags At the same time, the algorithm is not subject to mark the shape of the impact of the region, has good robustness)
