| Abstract(in English) | Given a set of points S, we call its outer border points as a border points set B. For convex S, it is easy to get B by choosing points each of which has the biggest projection to randomly chosen vectors. However, this is not the case for non convex S. In this paper, we propose a method that partitions the S into subsets each of which has enhanced convexity and gathers border points of them to get B. Probabilistic LSH-like searching scheme is also adapted to reduce computation cost. |
