Abstract

Making use of semantic information to achieve the high-level analysis and understanding is a hot issue currently. To address the problem of automatic recognition in the presence of significant geometric and topological variations, this paper proposed a 3D shape function recognition method by adopting the contextual relationship of shape parts. Firstly, it decomposed 3D shapes into the shape part sets with independent semantics and employed the technique of approximate convexity analysis. Then, it computed the contextual relationship of shape parts and on this basis, and adopted support vector machines to achieve the task of automatic recognition between shape parts. Experimental results show that the proposed method achieves higher the matching accuracy values and lower classification error rates, compared to the existing methods.
