Multi-lighting 3D face morphable model based on mesh resampling

This work describes a multi-lighting 3D face morphable model based on mesh resampling. Despite having realistic results and modeling automatically in 3D face synthesis, the morphable model depends on the unstable optical flow algorithm for model construction, and the model matching is not fitting for complex illumination. To improve modeling results, the mesh resampling method is used to overcome the key problem of model construction, the pixel-to-pixel alignments of prototypic faces. A multi-lighting model is also proposed to evaluate the illumination of the input facial image. The experimental results show these measurements have good performance.
