Estimating 3D Face Model and Facial Deformation from a Single Image Based on Expression Manifold Optimization
Facial expression modeling is central to facial expression recognition and expression synthesis for facial animation. Previous works reported that modeling the facial expression with low-dimensional manifold is more appropriate than using a linear subspace. In this paper, we propose a manifold-based 3D face reconstruction approach to estimating the 3D face model and the associated expression deformation from a single face image. In the training phase, we build a nonlinear 3D expression manifold from a large set of 3D facial expression models to represent the facial shape deformations due to facial expressions. Then a Gaussian mixture model in this manifold is learned to represent the distribution of expression deformation. By combining the merits of morphable neutral face model and the low-dimensional expression manifold, we propose a new algorithm to reconstruct the 3D face geometry as well as the 3D shape deformation from a single face image with expression in an energy minimization ...
