Georgios Th. Papadopoulos, Vasileios Mezaris, Ioannis Kompatsiaris, Michael G. Strintzis
2008 Proceedings of the 2008 international conference on Content-based image and video retrieval - CIVR '08  
In this paper, a motion-based approach for detecting highlevel semantic events in video sequences is presented.  ...  The latter is based on the observation that motion information from previous frames can provide valuable cues for interpreting the semantics present in a particular frame.  ...  This is based on a new representation for providing local-level motion information to HMMs and is different in nature from the 'points of interest'-based local-level analysis commonly used for dedicated  ...
