【摘要】 提出了一种基于等高线树和Strip树的等高线拓扑关系一致性化简算法,该算法可完全确保等高线在化简后不会发生自相交和相互间的相交,且化简后的等高线顶点集合是化简前等高线顶点集合的子集。更多还原

【Abstract】 A topologically consistent contour simplification algorithm based on contour-tree and strip-tree is put forward.This algorithm can ensure that contours not to take place self-intersection or intersect with each other after simplification,and the set of contour vertices after simplification is subset of the set of contour vertices before simplification.更多还原
