Emotional Avatars: Appearance Augmentation and Animation based on Facial Expression Analysis

PP: 461-469
Taehoon Cho, Jin-Ho Choi, Hyeon-Joong Kim, Soo-Mi Choi,
We propose an emotional facial avatar that portrays the userís facial expressions with an emotional emphasis, while achieving visual and behavioral realism. This is achieved by unifying automatic analysis of facial expressions and animation of realistic 3D faces with details such as facial hair and hairstyles. To augment facial appearance according to the userís emotions, we use emotional templates representing typical emotions in an artistic way, which can be easily combined with the skin texture of the 3D face at runtime. Hence, our interface gives the user vision-based control over facial animation of the emotional avatar, easily changing its moods.
