![]() We attach MANO to a standard parameterized 3D body shape model (SMPL), resulting in a fully articulated body and hand model (SMPL+H). MANO provides a compact mapping from hand poses to pose blend shape corrections and a linear manifold of pose synergies. ![]() The model is realistic, low-dimensional, captures non-rigid shape changes with pose, is compatible with standard graphics packages, and can fit any human hand. MANO is learned from around 1000 high-resolution 3D scans of hands of 31 subjects in a wide variety of hand poses. To cope with low-resolution, occlusion, and noise, we develop a new model called MANO (hand Model with Articulated and Non-rigid defOrmations). When scanning or capturing the full body in 3D, hands are small and often partially occluded, making their shape and pose hard to recover. Here we formulate a model of hands and bodies interacting together and fit it to full-body 4D sequences. Surprisingly, most methods treat the 3D modeling and tracking of bodies and hands separately. Capturing and replicating such coordinated activity is critical for virtual characters that behave realistically. Humans move their hands and bodies together to communicate and solve tasks.
