Abstract
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.

12. A facial image-processing method comprising:
-
illuminating a face with a first polarized light source that is selected so that specularly-suppressed reflective properties of the face can be ascertained;
illuminating the face with a second structured light source that projects a pattern onto the face, while simultaneously illuminating the face with the first polarized light source;
capturing both specularly-suppressed reflection data and structure data from the simultaneous illumination. - View Dependent Claims (13, 14, 15, 16)

17. A facial image processing system comprising:
-
a facial illumination system that is configured to provide multiple different light sources at the same time for illuminating a subject'"'"'s face; and
a data-capturing system configured to capture both structure data and reflectance data from the subject'"'"'s face when illuminated by the facial illumination system. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
