Analysis of human activities described by image sequences

Authors: François Brémond and Monique Thonnat


This paper describes a system for image sequence understanding. More precisely we address the issue of scenario recognition for scene interpretation systems. After presenting related works on scenario recognition, we first establish different requirements to describe human activities involved in video-surveillance applications. Then based on a model, we define a scenario as a combination of sub-scenarios. Depending on the type of combination (temporal or non temporal) we use an abductive diagnosis or an automaton to recognize the scenario. Then we explain through an example how to use the scenario representation. Finally we propose several mechanisms to obtain a real-time scenario recognition process.

Keywords: Behavior analysis, scene interpretation, image sequence understanding, knowledge-based system, real-time control, real-word application.
