A Model Based Method For Stereo Face Reconstruction

Face reconstruction is a long-standing and extremely challenging problem. In order to solve this problem more accurately and efficiently, In this paper, we propose a model based stereo method to reconstruct fine detailed 3D face with the calibrated face stereo images captured by stereo camera. Our model based stereo method can avoid the limited power of expressiveness in model based reconstruction and the mismatch appeared in stereo reconstruction. In the proposed method, the sparse landmarks detected from stereo images are employed to reconstruct coarse shape and posture parameters with 3d morphable model(3DMM). The detailed face will be gotten by per vertex deformation based on coarse shape according to illumination value, gradient and surface smooth terms, and the direction of per vertex deformation follows the direction of the vertex's normal, for which is the fastest changing direction of local mesh area. The experimental results show that our proposed method achieve high performance compared with the E-eos method.
