--- _id: '2115' abstract: - lang: eng text: The facial performance of an individual is inherently rich in subtle deformation and timing details. Although these subtleties make the performance realistic and compelling, they often elude both motion capture and hand animation. We present a technique for adding fine-scale details and expressiveness to low-resolution art-directed facial performances, such as those created manually using a rig, via marker-based capture, by fitting a morphable model to a video, or through Kinect reconstruction using recent faceshift technology. We employ a high-resolution facial performance capture system to acquire a representative performance of an individual in which he or she explores the full range of facial expressiveness. From the captured data, our system extracts an expressiveness model that encodes subtle spatial and temporal deformation details specific to that particular individual. Once this model has been built, these details can be transferred to low-resolution art-directed performances. We demonstrate results on various forms of input; after our enhancement, the resulting animations exhibit the same nuances and fine spatial details as the captured performance, with optional temporal enhancement to match the dynamics of the actor. Finally, we show that our technique outperforms the current state-of-the-art in example-based facial animation. author: - first_name: Amit full_name: Bermano, Amit H last_name: Bermano - first_name: Derek full_name: Bradley, Derek J last_name: Bradley - first_name: Thabo full_name: Beeler, Thabo last_name: Beeler - first_name: Fabio full_name: Zund, Fabio last_name: Zund - first_name: Derek full_name: Nowrouzezahrai, Derek last_name: Nowrouzezahrai - first_name: Ilya full_name: Baran, Ilya last_name: Baran - first_name: Olga full_name: Sorkine-Hornung, Olga last_name: Sorkine Hornung - first_name: Hanspeter full_name: Pfister, Hanspeter last_name: Pfister - first_name: Robert full_name: Sumner, Robert W last_name: Sumner - first_name: Bernd full_name: Bernd Bickel id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Markus full_name: Groß, Markus S last_name: Groß citation: ama: Bermano A, Bradley D, Beeler T, et al.
