摘要
这篇论文为决定等高线的起点建议一个新算法。新算法基于间隔树。结果显著地改进算法的效率。进一步,新策略被设计抑制穿的方向,产生轮廓忍受更有意义的信息。
This paper proposes a new algorithm for determining the starting points of contour lines. The new algorithm is based on the interval tree. The result improves the algorithm's efficiency remarkably. Further, a new strategy is designed to constrain the direction of threading and the resulting contour bears more meaningful information.
