Human motion data analysis and retrieval based on 3D feature extraction
基于三维特征提取的人体运动数据分析和检索

Based on 3D features for time and space relationship of each human joint,a kind of temporal-spatial features was proposed in this paper,which can process local temporal-spatial features of each joints.3D features can represent a part of the whole motion independently and avoid contacting with original motion data and eliminate curse of dimensionality.Experimental results show that the approaches are effective for motion data analysis,which can be used in intelligent analysis for motion semantics.
