  1. Scene Understanding perception, multi-sensor fusion, spatio-temporal reasoning and activity recognition. Francois BREMOND Orion project-team, INRIA Sophia Antipolis, FRANCE Francois.Bremond@sophia.inria.fr http://www-sop.inria.fr/orion/orion-eng.html Key words: Artificial intelligence, knowledge-based systems, cognitive vision, human behavior representation, scenario recognition

  2. A scene understanding platform: real-time interpretation of videos from pixels to events Segmentation Classification Scenario Recognition Tracking Alarms access to forbidden area 3D scene model Scenario models A priori Knowledge

  3. Video Understanding Applications metro station monitoring airport monitoring train monitoring building control access

  4. ETISEO: performance evaluation depends on sensors (position, type) and scenes conditions strong perspective shadows tiny objects lighting conditions clutter close view

  5. ETISEO: selection of 6 sites for ETISEO video acquisition.

  6. Classification into more than 8 classes (e.g. Person, Groupe, Train) based on 2D and 3D descriptors (position, 3D ratio height/width, …)

  7. Vandalism in metro station

  8. Fighting in metro station
