PhysAvatar: Learning the Physics of Dressed 3D Avatars from Visual Observations

no code implementations5 Apr 2024 Yang Zheng, Qingqing Zhao, Guandao Yang, Wang Yifan, Donglai Xiang, Florian Dubost, Dmitry Lagun, Thabo Beeler, Federico Tombari, Leonidas Guibas, Gordon Wetzstein

This marks a significant advancement towards modeling photorealistic digital humans using physically based inverse rendering with physics in the loop.

Diffusion Shape Prior for Wrinkle-Accurate Cloth Registration

no code implementations10 Nov 2023 Jingfan Guo, Fabian Prada, Donglai Xiang, Javier Romero, Chenglei Wu, Hyun Soo Park, Takaaki Shiratori, Shunsuke Saito

Registering clothes from 4D scans with vertex-accurate correspondence is challenging, yet important for dynamic appearance modeling and physics parameter estimation from real-world data.

Dressing Avatars: Deep Photorealistic Appearance for Physically Simulated Clothing

no code implementations30 Jun 2022 Donglai Xiang, Timur Bagautdinov, Tuur Stuyck, Fabian Prada, Javier Romero, Weipeng Xu, Shunsuke Saito, Jingfan Guo, Breannan Smith, Takaaki Shiratori, Yaser Sheikh, Jessica Hodgins, Chenglei Wu

The key idea is to introduce a neural clothing appearance model that operates on top of explicit geometry: at training time we use high-fidelity tracking, whereas at animation time we rely on physically simulated geometry.

Modeling Clothing as a Separate Layer for an Animatable Human Avatar

no code implementations28 Jun 2021 Donglai Xiang, Fabian Prada, Timur Bagautdinov, Weipeng Xu, Yuan Dong, He Wen, Jessica Hodgins, Chenglei Wu

To address these difficulties, we propose a method to build an animatable clothed body avatar with an explicit representation of the clothing on the upper body from multi-view captured videos.

MonoClothCap: Towards Temporally Coherent Clothing Capture from Monocular RGB Video

no code implementations22 Sep 2020 Donglai Xiang, Fabian Prada, Chenglei Wu, Jessica Hodgins

A differentiable renderer is utilized to align our captured shapes to the input frames by minimizing the difference in both silhouette, segmentation, and texture.

Single-Network Whole-Body Pose Estimation

2 code implementations ICCV 2019 Gines Hidalgo, Yaadhav Raaj, Haroon Idrees, Donglai Xiang, Hanbyul Joo, Tomas Simon, Yaser Sheikh

We present the first single-network approach for 2D~whole-body pose estimation, which entails simultaneous localization of body, face, hands, and feet keypoints.

You2Me: Inferring Body Pose in Egocentric Video via First and Second Person Interactions

1 code implementation CVPR 2020 Evonne Ng, Donglai Xiang, Hanbyul Joo, Kristen Grauman

The body pose of a person wearing a camera is of great interest for applications in augmented reality, healthcare, and robotics, yet much of the person's body is out of view for a typical wearable camera.

Surface Normals in the Wild

no code implementations ICCV 2017 Weifeng Chen, Donglai Xiang, Jia Deng

We study the problem of single-image depth estimation for images in the wild.

Semantic Object Parsing with Local-Global Long Short-Term Memory

no code implementations CVPR 2016 Xiaodan Liang, Xiaohui Shen, Donglai Xiang, Jiashi Feng, Liang Lin, Shuicheng Yan

The long chains of sequential computation by stacked LG-LSTM layers also enable each pixel to sense a much larger region for inference benefiting from the memorization of previous dependencies in all positions along all dimensions.
