Facial Expression Training System using Bilinear Shape Model

We introduce a facial expression training system using the bilinear shape model which helps people to practice making a facial expression. The user face on the camera preview screen is reconstructed into a 3D face model and the model is transformed to blend shape model which represents the facial expression. This way, the system can precisely analyze the facial expression of the user. With target 3D face model appearing on the screen, the 3D face model changes its facial expression, it leads the user to change his facial expression to become look like same. The system recognizes whether the facial expression of the user is same with the one of 3D face model. As the system gives the various missions to user to change his facial expression, user can practice the facial expression. It can be used for bell's palsy patient who needs face rehabilitation exercise or someone who need to practice unique facial expression such as stewardess smile or facial mimicry.
