The authors propose and compare two types of model-based facial motion coding schemes, i.e., synthesis by rules and synthesis by parameters. In synthesis by rules, facial motion images are synthesized on the basis of rules extracted by analysis of training image samples that include all of the phonemes and coarticulation. This system can be utilized as an automatic facial animation synthesizer from text input or as a man-machine interface using the facial motion image. In synthesis by parameters, facial motion images are synthesized on the basis of a code word index of speech parameters. Experimental results indicate good performance for both systems, which can create natural facial-motion images with very low transmission rate. Details of 3-D modeling, algorithm synthesis, and performance are discussed.
