SMPL-X is a major update to the SMPL body model that adds an expressive face and fully articulated hands. If you use SMPL, this is a straightforward upgrade that improves realism and allows you to capture facial expressions and gestures. We also provide SMPLify-X to estimate SMPL-X from a single image. This is a major update to SMPlify in several senses: (1) we detect 2D features corresponding to the face, hands, and feet and fit the full SMPL-X model to these; (2) we train a new neural network pose prior using a large MoCap dataset; (3) we define a new interpenetration penalty that is both fast and accurate; (4) we automatically detect gender and the appropriate body models (male, female, or neutral); (5) our PyTorch implementation achieves a speedup of more than 8x over Chumpy.
