A 3D facial combination model based on mesh resampling

In this paper, we describe a combination model for 3D facial synthesis. To construct the model it is fundamental to compute the dense point-to-point alignments among the prototypic faces acquired by Cyberware scanner. The proposed mesh resampling method overcome the alignments by the same resampling criterion to all prototypes. From the aligning prototypes the linear combination facial model is constructed. Matching the model to given facial image, the 3D face would be built automatically. To accelerate the model matching and expand the model fitting complex illumination, the multiresolution model and multilight model are designed. Although sharing the basic idea with the morphable model, the combination model has innovations in alignment strategy and illumination model. The experimental results show that the combination model have good performance in 3D face modelling.
