3D digital topological relationship analysis for spatial entity with fuzzy boundary

This paper discusses the topological relations between 3D spatial entities with fuzzy boundaries, and introduces a regular block model-based computable topological analysis approaches. Based on 3D digital topology theory, a regular block is defined with 6-connectiviity and the interior, the fuzzy boundary and the k-order 6 neighborhoods of a spatial entity with fuzzy boundary are defined. Furthermore, a new topological relationship analysis...
