Corrective 3D Reconstruction of Lips from Monocular Video

P. Garrido, M. Zollhöfer, C. Wu, D. Bradley, P. Pérez, T. Beeler, C. Theobalt

ACM Transactions on Graphics (Proceedings of SIGGRAPH Asia). 2016. (Macao)

We present a method to reconstruct detailed and expressive lip shapes from monocular RGB video. To this end, we learn the difference between inaccurate lip shapes found by a monocular facial capture method, and the true 3D lip shapes reconstructed using a high-quality multi-view system, and finally infer accurate lip shapes in a regression framework.

An Anatomically Constrained Local Deformation Model for Monocular Face Capture

C. Wu, D. Bradley, M. Gross, T. Beeler

We present a new anatomically-constrained local face model and fitting approach for tracking 3D faces from 2D motion data in very high quality. In contrast to traditional global models, we propose a local deformation model composed of many small subspaces spatially distributed over the face, and introduce anatomical subspace skin thickness constraints.

FaceDirector: Continuous Control of Facial Performance in Video

C. Malleson, J.-C. Bazin, O. Wang, D. Bradley, T. Beeler, A. Hilton, A. Sorkine-Hornung

We present a method to continuously blend between multiple facial performances of an actor, which can contain different expressions or emotional states. As an example, given sad and angry video takes of a scene, our method empowers a movie director to specify arbitrary weighted combinations and smooth transitions between the two takes in post-production.
