Towards 3D Communications: Real Time Emotion Driven 3D Virtual Facial Animation
Wei Zhou, Nan Xiang, Xiaojian Zhou · 2011
In this paper, we provide a novel algorithm for building real time 3D virtual facial animation of avatar by drawing facial expression features of real characters. This algorithm first (automatically) labels the feature points of user's facial imagines drew from camera. Then sequentially estimates the emotional state of user's face expressions by Hidden Markov Model. At last construct the avatar's facial animation according to these emotional states. We explore the complex expression space by outputting synthetic facial animations blended by 6 standard facial expressions.
