Combination of Interior and Exterior Shape Descriptors for 3D Model Retrieval
並列摘要
In this paper, a 3D model retrieval system will be proposed based on the combination of interior and exterior 3D shape information. The shell grid descriptor (SGD) and 3D Angular Radial Transformation (3D-ART) are used for extracting the interior shape information. Two projection descriptors, ART-based elevation descriptor (AED) and principal plane descriptor (PPD) are adopted as the 3D exterior features. Finally, the two interior features, SGD and 3D-ART, as well as two exterior features, AED and PPD, are combined in an attempt to improve retrieval result. Experimental results show that the proposed method is superior to other descriptors.
