Abstract
Facial animation values are generated using a sequence of facial image frames and synchronously captured audio data of a speaking actor. In the technique, a plurality of visual-facial-animation values are provided based on tracking of facial features in the sequence of facial image frames of the speaking actor, and a plurality of audio-facial-animation values are provided based on visemes detected using the synchronously captured audio voice data of the speaking actor. The plurality of visual facial animation values and the plurality of audio facial animation values are combined to generate output facial animation values for use in facial animation.
