A Unified Framework for Mesh Segmentation and Part Annotation

This paper proposed a unified framework to generate consistent segmentation and annotate part semantic for 3D mesh simultaneously. The core idea of the proposed framework is to bridge the semantic gap between low-level geometry feature and high-level semantic feature by structure ontology. The structure ontology makes a consistence representation for mesh structure, geometry feature, semantic concept and semantic rules. So it can be used in the process of segmentation and part annotation. Comparing with the previous work, the proposed framework has the two distinctive characters. Firstly, it can avoid inconsistence segmentation problems deduced from existing segmentation algorithms. Secondly, it can recognize part semantic automatically by defined semantic rules. Finally, this paper shows some experiment results to further verify the effect of the proposed framework.
