Skeleton Extraction from Point Clouds based on Discrete Curvature

Vol. 11  No. 11  pp. 53-57


We present an algorithm to extract the skeleton from unorganized point clouds by exploiting a discrete curvature. In general, the result of skeleton extraction depends on the ordering of sample points and the geometric properties of consecutive points in the order. In this paper, we utilize the discrete curvature defined by three consecutive sample points to extract an order from points. Our method is more intuitive than the previous methods and can extract the skeleton from point clouds which resembles the global shape of the clouds.
