| 英文摘要 | Many shape co-segmentation methods employ multiple descriptors to measure the similarities between parts of a set of shapes in a descriptor space. Different shape descriptors characterize a shape in different aspects. Simply concatenating them into a single vector might greatly degrade the performance ofthe co-analysis in the presence of irrelevant and redundant information. In this paper, we propose an approach to fuse multiple descriptors for unsupervised co-segmentation of a set of shapes from the same family. Starting from the over-segmentations of shapes, our approach generates the consistent segmentationby performing the spectral clustering in a fused space of shape descriptors. The core of our approach is to seek for an optimal combination of affinity matricesof different descriptors so as to alleviate the impact of unreliable and irrelevant features. More specially, we introduce a local similarity based affinityaggregation spectral clustering algorithm, which assumes the local similarities are more reliable than far-away ones. Experimental results show the efficiencyof our approach and improvements over the state-of-the-art algorithms on the benchmark datasets. Crown Copyright (C) 2013 Published by Elsevier Ltd.
