NICP: Neural ICP for 3D Human Registration at Scale

We propose a novel localized Neural Field (LoVD), the first self-supervised task for tuning neural fields (INT), and an efficient (takes less than a minute) scalable registration pipeline (NSR), that works with out-of-distribution data (partial point clouds, clutter, different poses, …).

Interaction Replica: Tracking human–object interaction and scene changes from human motion

Given the wearable sensors and the interactive environment, we want to estimate human and object positions and achieve visually plausible results.

CloSe: A 3D Clothing Segmentation Dataset and Model

We propose a fine-grained dataset for 3D human clothing segmentation (CloSe-D), the first learning-based 3D clothing segmentation model (CloSe-Net), and an interactive tool for refining 3D segmentation labels (CloSe-T)

NSF: Neural Surface Fields for Human Modeling from Monocular Depth

The Neural Surface Fields (NSF) defines a Neural Field on the level set of an implicit representation, providing a continuous and flexible function representation on 3D geometries. We apply it in an avatarization pipeline, learning animatable avatars with pose-dependent deformations starting from a sparse set of partial depth views.

Object pop-up: Can we infer 3D objects and their poses from human interactions alone?

We show that an unorganized 3D human point cloud provides enough information to infer a 3D interacted object, opening new directions in the human-object interaction research. We also analyze the impact of different levels of information and a saliency study about the geometrical features of the input human point cloud.
