Abstract
Level set method is a numerical analysis tool for the computation of propagating interfaces. In order to accelerate and strengthen numerical implementations of level set method, this paper proposed a set of auxiliary algorithms, i.e., simplified scanning based distance function construction, curve inside and outside labeling algorithm, and scanning based extension of velocity. With the former two algorithms, the signed distance function used as level set function can be constructed faster and more accurate. And the last algorithm makes the curve evolution by level set method more robust. The numerical tests showed efficiencies of the proposed algorithms.
