TwinFaces: Seamless Textures for Rendering Head Models

TwinFaces, a new technique for the automatic generation of facial textures is presented in this paper. Multiple views from the individual, taken under moderately controlled illumination conditions, are combined to create the seamless texture using a wavelet-based technique. Since the method relies on a set of particular feature points of the MPEG-4 facial and body animation (FBA) standard, it can be easily integrated with applications using the same standard. A post-processing technique for pictures taken outdoors has been also integrated into TwinFaces to compensate for non-uniform illumination conditions. The wavelet-based approach has shown to be more flexible than previous approaches to remove the artificial seam lines produced by the blending of the different views involved in the texture generation
