Abstract

Abstract

En 中文
Contrary to the 2D case, a 3D hole is not a subset of the 3D space. It is therefore not possible to use connected components search algorithms for detecting and suppressing 3D holes. In this paper, we propose an algorithm for suppressing 3D holes. It is based on properties of the previously introduced notion of topological number. Our algorithm is linear in time and it allows to control the size of the holes which are closed. As far as we know, this is the first ID holes closing algorithm. (C) 2002 Elsevier Science B.V.
