Abstract
An animation system wherein a machine learning model is adopted to generate animated facial actions based on parameters obtained from a live actor. Specifically, the anatomical structure such as a facial muscle topology and a skull surface that are specific to the live actor may be used. A muscle structure of simplified 'pseudo' muscles that approximate the actual muscle topology but with reduced degree of freedom is determined to improve computational efficiency.
