In the described embodiment, methods and systems for processing facial
image data for use in animation are described. In one embodiment, a
system is provided that illuminates a face with illumination that is
sufficient to enable the simultaneous capture of both structure data,
e.g. a range or depth map, and reflectance properties, e.g. the diffuse
reflectance of a subject's face. This captured information can then be
used for various facial animation operations, among which are included
expression recognition and expression transformation.
