Physics-based muscle model for mouth shape control

Human image synthesis by computer graphics is essential to a virtual agent in human interface and entertainment visual system. In this paper, a muscle model is proposed to create a super realistic human face. There are several researches to synthesize human expression, however, a research about mouth shape control in conversation is limited to our group. Especially, we try to choose and modify muscles which are good for mouth shape generation to realize a natural conversation scene. Basic mouth shape is defined by measuring the real image captured by camera. We also try to make animation using standard phoneme duration to realize lip-sync.
