| 摘 要： | 对复连通区域填充算法进行了细致的研究,提出一种新的扫描线填充算法。该算法先对目标边界进行标注,提供判断条件,然后用扫描线进行填充;该算法不仅适用于单连通区域,而且也适用于复杂区域的填充。该算法效率高,通用性强,实现简单,填充准确。

| Abstract: | Filling algorithm of the complex connecting area is studied and a new scan line algorithm for filling area is presented. Using this algorithm, every edge pixel for judgment is labelled, then the area is filled using the scan line. This algorithm is applied not only to simple connecting area, but also to the complex area. And it is efficient, flexible, easy and exact. |
