Temporal Constraints for Video Interpretation
Van-Thinh Vu, François Brémond · 2002
Abstract. This paper presents an original approach for temporal scenario recognition for video interpretation. We propose a declarative model to represent scenarios and we use a logic-based approach to recognize pre-defined scenario models. To speed up the recognition process, we propose a new method to process the temporal operators of interval algebra and a method to extend the time interval of recognized scenarios. We have tested our representation formalism and the inference engine on two real video sequences. 1
