We present a non-rigid registration technique that achieves spatial, photometric, and visibility accuracy. It lets us photo-realistically augment 3D deformable surfaces under complex illumination con- ditions and in spite of severe occlusions. There are many ap- proaches that address some of these issues but very few that si- multaneously handle all of them as we do. We use triangulated meshes to model the geometry and introduce explicit visibility maps as well as separate illumination parameters for each mesh vertex. We cast our registration problem in an Ex- pectation Maximization framework that allows robust and fully au- tomated operation. It provides explicit illumination and occlusion models that can be used for rendering purposes.
