Analyse de mouvement facial dur des images monoculaires avec application aux télécommunications: Couplage de la compréhension de l'expression et du suivi de la pose du visage

Abstract : Facial animation has become an active research topic in telecommunications. This field aims at replacing traditional communication systems by more human oriented solutions based on virtual reality technology. This work exposes in detail novel techniques to study non-rigid facial motion coupled with head pose tracking. Specific feature analysis methods have been developed to study each one of the features that we believe to be the most relevant while communicating: eye, eyebrows and mouth. We have designed image-processing algorithms based on the physiognomy of the speaker and individual motion models that exploit the correlation existing among the analyzed features. The analysis techniques have been first developed for faces being analyzed from a frontal point of view and then, using the pose parameters derived from the tracking and the 3D data of the clone, they have been adapted to allow the speaker more freedom of movement in front of the camera. This adaptation is possible by redefining the 2D analysis models over the the clone (3D head model), in 3D, and reinterpreting the analyzed data in accordance with the 3D location of the head. This report contains experimental results, main contributions and relevant bibliographic references of the overall research
