Abstract
This paper presents a method for computing topological type of voxel models. Our method counts a number of foreground and background components in 124 neighbor voxels of each voxel and topological type is determined by their configurations. This enables us robust estimation of topological elements. In addition, we also apply morphology-like operations on voxels in order to fill mis-judged voxels. This topological classification is efficient for polygonization of non-manifold objects from voxel models. Indeed, we demonstrate a polygonization of thin-plate objects by using classification results.
