Abstract (en)

[origin: WO2022208440A1] A neural human performance capture framework (MVS-PERF) captures the skeleton,body shape and clothes displacement, and appearance of a person from a set of calibratedmultiview images. It addresses the ambiguity of predicting the absolute position in monocularhuman mesh recovery, and bridges the volumetric representation from NeRF toanimation-friendly performance capture. MVS-PERF includes three modules to extract featuremaps from multiview images and fuse them to a feature volume, regress the feature volume to anaked human parameters vector, generating an SMPL-X skin-tight body mesh with a skeletalpose, body shape, and expression, and leverage a neural radiance field and a deformation field toinfer the clothes as the displacement on the naked body using differentiable rendering. Clothedbody mesh is obtained by adding the interpolated displacement vectors to the SMPL-X skin-tightbody mesh vertices. The obtained radiance field is used for free-view volumetric rendering of theinput subject.
