Fast Shape Re-ranking with Neighborhood Induced Similarity Measure

摘要

In this paper, we address the shape retrieval problem by casting it into the task of identifying "authority" nodes in an inferred similarity graph and also by re-ranking the shapes. The main idea is that the average similarity between a node and its neighboring nodes takes into account the local distribution and therefore helps modify the neighborhood edge weight, which guides the re-ranking. The proposed approach is evaluated on both 2D and 3D shape datasets, and the experimental results show that the proposed neighborhood induced similarity measure significantly improves the shape retrieval performance.
