Indexing 3D Scenes Using the Interaction Bisector Surface

摘要: The spatial relationship between different objects plays an important role in defining the context of scenes. Most previous 3D classification and retrieval methods take into account either individual geometry or simple relationships them such as contacts adjacencies. In this article we propose a new method for based on Interaction Bisector Surface (IBS), subset Voronoi diagram defined objects. IBS is sophisticated representation that describes topological whether object wrapped in, linked to, tangled with others, well geometric distance We hierarchical framework to index scenes by examining both structure attributes IBS. topology-based indexing can compare relations without being severely affected local details object. Geometric also be applied comparing precise way which are interacting one another. Experimental results show our effective at content-based retrieval.
