Physics-based muscle model for mouth shape control
H. Sera, Shigeo Morishima, Demetri Terzopoulos · 2002
Human image synthesis by computer graphics is essential to a virtual agent in human interfaces and entertainment visual systems. In this paper, a muscle model is proposed to create a super realistic human face. There are several researches to synthesize human expression, however, 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.
