REWIND: Real-Time Egocentric Whole-Body Motion Diffusion with Exemplar-Based Identity Conditioning

CVPR 2025poster

We present REWIND (Real-Time Egocentric Whole-Body Motion Diffusion), a one-step diffusion model for real-time, high-fidelity human motion estimation from egocentric image inputs. While an existing method for egocentric whole-body (i.e., body and hands) motion estimation is non-real-time and acausal…

Codec Avatar Studio: Paired Human Captures for Complete, Driveable, and Generalizable Avatars

NeurIPS 2024poster

To build photorealistic avatars that users can embody, human modelling must be complete (cover the full body), driveable (able to reproduce the current motion and appearance from the user), and generalizable (_i.e._, easily adaptable to novel identities). Towards these goals, _paired_ captures, that…

Fast Registration of Photorealistic Avatars for VR Facial Animation

ECCV 2024poster

"Virtual Reality (VR) bares promise of social interactions that can feel more immersive than other media. Key to this is the ability to accurately animate a personalized photorealistic avatar, and hence the acquisition of the labels for headset-mounted camera (HMC) images need to be efficient and ac…

LiP-Flow: Learning Inference-Time Priors for Codec Avatars via Normalizing Flows in Latent Space

ECCV 2022poster

"Neural face avatars that are trained from multi-view data captured in camera domes can produce photo-realistic 3D reconstructions. However, at inference time, they must be driven by limited inputs such as partial views recorded by headset-mounted cameras or a front-facing camera, and sparse facial…

Robust Egocentric Photo-Realistic Facial Expression Transfer for Virtual Reality

CVPR 2022poster

Social presence, the feeling of being there with a "real" person, will fuel the next generation of communication systems driven by digital humans in virtual reality (VR). The best 3D video-realistic VR avatars that minimize the uncanny effect rely on person-specific (PS) models. However, these PS mo…

SimPoE: Simulated Character Control for 3D Human Pose Estimation

CVPR 2021poster

Accurate estimation of 3D human motion from monocular video requires modeling both kinematics (body motion without physical forces) and dynamics (motion with physical forces). To demonstrate this, we present SimPoE, a Simulation-based approach for 3D human Pose Estimation, which integrates image-bas…

Supervision-by-Registration: An Unsupervised Approach to Improve the Precision of Facial Landmark Detectors

CVPR 2018poster

In this paper, we present supervision-by-registration, an unsupervised approach to improve the precision of facial landmark detectors on both images and video. Our key observation is that the detections of the same landmark in adjacent frames should be coherent with registration, i.e., optical flow.…

Realtime Multi-Person 2D Pose Estimation Using Part Affinity Fields

CVPR 2017oral

We present an approach to efficiently detect the 2D pose of multiple people in an image. The approach uses a nonparametric representation, which we refer to as Part Affinity Fields (PAFs), to learn to associate body parts with individuals in the image. The architecture encodes global context, allowi…
