PDE Face: A Novel 3D Face Model

By Y. Sheng, P. Willis, Gabriela Gonzalez Castro and Hassan Ugail

Abstract

YesWe introduce a novel approach to face models, which\ud exploits the use of Partial Differential Equations (PDE) to\ud generate the 3D face. This addresses some common\ud problems of existing face models. The PDE face benefits\ud from seamless merging of surface patches by using only a\ud relatively small number of parameters based on boundary\ud curves. The PDE face also provides users with a great\ud degree of freedom to individualise the 3D face by\ud adjusting a set of facial boundary curves. Furthermore, we\ud introduce a uv-mesh texture mapping method. By\ud associating the texels of the texture map with the vertices\ud of the uv mesh in the PDE face, the new texture mapping\ud method eliminates the 3D-to-2D association routine in\ud texture mapping. Any specific PDE face can be textured\ud without the need for the facial expression in the texture\ud map to match exactly that of the 3D face model
