NRDF: Neural Riemannian Distance Fields for Learning Articulated Pose Priors

no code implementations5 Mar 2024 Yannan He, Garvita Tiwari, Tolga Birdal, Jan Eric Lenssen, Gerard Pons-Moll

Faithfully modeling the space of articulations is a crucial task that allows recovery and generation of realistic poses, and remains a notorious challenge.

CloSe: A 3D Clothing Segmentation Dataset and Model

no code implementations22 Jan 2024 Dimitrije Antić, Garvita Tiwari, Batuhan Ozcomlekci, Riccardo Marin, Gerard Pons-Moll

Additionally, we propose CloSe-Net, the first learning-based 3D clothing segmentation model for fine-grained segmentation from colored point clouds.

Pose-NDF: Modeling Human Pose Manifolds with Neural Distance Fields

1 code implementation27 Jul 2022 Garvita Tiwari, Dimitrije Antic, Jan Eric Lenssen, Nikolaos Sarafianos, Tony Tung, Gerard Pons-Moll

The resulting high-dimensional implicit function can be differentiated with respect to the input poses and thus can be used to project arbitrary poses onto the manifold by using gradient descent on the set of 3-dimensional hyperspheres.

Neural-GIF: Neural Generalized Implicit Functions for Animating People in Clothing

1 code implementation ICCV 2021 Garvita Tiwari, Nikolaos Sarafianos, Tony Tung, Gerard Pons-Moll

Neural-GIF can be trained on raw 3D scans and reconstructs detailed complex surface geometry and deformations.

SIZER: A Dataset and Model for Parsing 3D Clothing and Learning Size Sensitive 3D Clothing

1 code implementation ECCV 2020 Garvita Tiwari, Bharat Lal Bhatnagar, Tony Tung, Gerard Pons-Moll

SizerNet allows to estimate and visualize the dressing effect of a garment in various sizes, and ParserNet allows to edit clothing of an input mesh directly, removing the need for scan segmentation, which is a challenging problem in itself.

Multi-Garment Net: Learning to Dress 3D People from Images

6 code implementations ICCV 2019 Bharat Lal Bhatnagar, Garvita Tiwari, Christian Theobalt, Gerard Pons-Moll

We present Multi-Garment Network (MGN), a method to predict body shape and clothing, layered on top of the SMPL model from a few frames (1-8) of a video.
