摘要：A facial expression is defined by a time sequence of facial images. Various kinds of facial expressions can be generated from a basic facial image sequence by modifying the time generation functions. This paper describes a 3-D image generation method for facial expressions that uses three kinds of time generation functions. The facial expressions generated by these functions are compared and a method that breaks observed facial expressions down into these time generation functions is presented.
