- 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 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).

+ Control Interface for a Synthetic Face :
We manage to automatically generate a simple, intuitive control interface to manipulate emotional facial expressions on a synthetic face. The interface is based on the analysis of real human facial expressions.
