摘要
介绍了图形轮廓线的夹角比较识别算法。确定初始搜索点和初始搜索边 ,由初始的点和边开始查找出与之关联的边 ,计算各关联边在搜索方向的矢量 ,通过比较各边的矢量与参考矢量的夹角确定出轮廓边 ,重复上述过程直至轮廓边闭合为止。
This paper presents the algorithm on identifying the outline of the graphics by comparing angles. Firstly the initial node and edge are determined, from the node and edge, the associated edges is searched, and vectors of every edge in searching direction is calculated, the contour edge is decided by comparing the angles formed by the vectors of edges passed through the searching node and the reference vector, repeat this process until the contour edges are closed.
