Effects of facial color on virtual facial image synthesis for dynamic facial color and expression under laughing emotion

Human facial color was applied to the affect display of virtual facial image, emotional evaluation, individual identification, and remote health care. We dynamically analyzed facial color under the emotional change of laughing by the simultaneous measurement of facial image and facial skin temperature, and proposed a dynamic facial color model. In this paper, on the basis of the proposed dynamic facial color model under laughing emotion, we analyze the effects of facial color on virtual facial image synthesis for dynamic facial color and expression of smile by using an average facial image of 68 females. Sensory evaluation demonstrates the effectiveness of dynamic facial color for the affect display of virtual facial image under laughing emotion.
