Research

My main research interests are directed along developing statistical models and machine learning algorithms for:

human tracking and activity analysis
image and scene representation modeling
sequence analysis and multimedia content analysis.

Events

NEW: Festival de Robotique 2013 ! A l'occasion de ce festival, mon groupe 'Perception et Activity Understanding' présentera les resultats du projet Européen HUMAVIPS dans lequel il a contribué pour la perception audio-visuelle des personnes et de leurs comportement non-verbaux.

I have organised a summer school on Human Activity and Vision in October 2012.
I co-organised a workshop on Interactive Human Behavior Analysis in Open or Public Spaces in November 2011 in Amsterdam, as part of the International joint Conference on Ambient Intelligence (AmI).
