【摘要】 提出一种基于格网的开曲线连通域扩展算法。首先将格网边界点与开曲线端点按逆时针方向存入动态数组中,并建立包含拓扑结构关系的数据结构,然后判断出参加连通域扩展的点并设计扩展算法,最后生成一个等值线连通区域矢量化的图形文件。更多还原

【Abstract】 In this paper, we put forward an algorithm of connecting open contours based on grid data. First,we save boundary points, begin point and end point of an open contour in a dynamic array and create data structure including topographic relationship,then calculate to find connecting points,finally,create vector graphs.更多还原
