A SIMPLE AND EFFICIENT APPROACH FOR 3D MODEL DECOMPOSITION

Number of 3D models is growing every day.Segmentation of such models has recently attracted lot ofattentions. In this paper we propose a two-phase approach forsegmentation of 3D models. We leveraged a well-known fact fromelectrical physics for both initial segment specification andboundary detections. The first phase tries to locate the initialsegments having higher charge density while the second phase,leverages the minima rule and geodesic distance to find theboundary parts in the concave areas. The proposed approach hasa great advantage over the similar approach proposed by Wuand Levine [1]. The experimental result on the SHREC 2007dataset show the promising results for partial matching in 3Dmodel retrieval.
