1. A method of synthesizing realistic facial deformations for a computer graphics model of a face, including fine-scale detail such as skin wrinkling, the method comprising: (a) capturing data of a face including fine-scale detail for a plurality of facial expressions; (b) learning a model of how the fine-scale detail observed in the data of (a) can be predicted from coarser-scale facial motion data; (c) synthesizing fine-scale detail for the computer graphics model of the face based on the input of novel coarser-scale facial motion data using the learned model of (b); and (d) displaying the graphics model on a viewer readable screen.
