A topologically consistent contour simplification algorithm based on contour-tree and strip-tree
Yehua Sheng · Cehui kexue · 2008
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.
