Similar Motion Retrieval for Dynamic 3D Mesh Based on Modified Shape Distributions

Abstract

A similar motion search and retrieval system for dynamic 3D mesh is presented based on a modified shape distribution algorithm. In this paper, three fundamental functions for efficient retrieval have been developed: feature extraction, motion segmentation, and matching. Stable shape feature representation of 3D models has been realized by the modified shape distribution algorithm. Segmentation has been carried out by analyzing the degree of motion using the extracted feature vectors. Then, similar motion retrieval has been achieved employing the dynamic programming in the feature vector space.
