3D mesh video retrieval: A survey

This survey addresses methodologies for 3D mesh video retrieval including 3D mesh video action/motion retrieval and 3D mesh video facial expression recognition. They all involve retrieval procedures and, consequently, classification methods in order to identify similar actions/motions and facial expressions. The approaches are primarily categorized according to the 3D model representation that they use and their feature extraction and classification methods. Comparative data for the most promising methods is given, mainly on publicly available datasets.
