- Research activities: I am currently a PhD student under supervision of Renaud Seguier. The subject of my thesis is the Facial Expressiveness of Virtual Characters. You can checkout a few videos of my results so far : please refer to my publications list for my details. + Facial Expression Analysis : We aim at capturing and understanding how facial element move when performing facial expressions. We identify and interpret the expressions as a 2D point in our continuous facial expression disk. The expressions can be imitated by a virtual character who is commanded by the expression disk (last video on the right). Facial Expressions Tracking Online Analysis Online Analysis 2 Real-time Analysis and Imitation of Expressions + Facial Expression Retargeting : We developped a technique to retarget facial expressions from a source face (typically a human subject) onto a target face (2D or 3D virtual character). Results*:
