I am a Ph.D. student at UC Berkeley, working on computer vision and graphics, advised by Angjoo Kanazawa.

I did my undergrad at Jiao Tong University and got my master from Columbia. I have spent two summers at Adobe Research in 2021 and 2022, working with Bryan Russell.


I am currently interested in non-rigid 3D reconstruction and neural rendering. Particularly, I am excited about photorealistic capture of dynamics in-the-wild from consumer-level devices.

Monocular Dynamic View Synthesis: A Reality Check
Hang Gao, Ruilong Li, Shubham Tulsiani, Bryan Russell, Angjoo Kanazawa
NeurIPS, 2022
project page / arXiv / video / code

We show a discrepancy between the practical captures and the existing experimental protocols in dynamic view synthesis from monocular video.

Long-term Human Motion Prediction with Scene Context

Understanding scene context from an image helps to predict long-term, diverse human motion in 3D.

Deformable Kernels: Adapting Effective Receptive Fields for Object Deformation
Hang Gao*, Xizhou Zhu*, Steve Lin, Jifeng Dai
ICLR, 2020
project page / arXiv / code

By learning an instance-adaptive convolutional operator through 2D deformation in kernel space, we can adapt the effective receptive field at runtime.

Spatio-Temporal Action Graph Networks
Roei Herzig*, Elad Levi*, Huijuan Xu*, Hang Gao, Eli Brosh, Xiaolong Wang, Amir Globerson, Trevor Darrell
ICCV Workshop, 2019

We model video as a spatial-temporal relational graph for action recognition and find that the second order affinity (affinity between edges) is surprisingly helpful.

Disentangling Propagation and Generation for Video Prediction
Hang Gao*, Huazhe Xu, Qi-Zhi Cai, Ruth Wang, Fisher Yu, Trevor Darrell
ICCV, 2019

High fidelity video prediction is easier if we disentangle the flow propagation from frame generation.

Low-shot Learning via Covariance-Preserving Adversarial Augmentation Networks
Hang Gao, Zheng Shou, Alireza Zareian, Hanwang Zhang, Shih-Fu Chang
NeurIPS, 2018

We use learned feature augmentation to train low-shot classifiers.

AutoLoc: Weakly-supervised Temporal Action Localization in Untrimmed Videos
Zheng Shou, Hang Gao, Lei Zhang, Kazuyuki Miyazawa, Shih-Fu Chang
ECCV, 2018
arXiv / code

We propose a weakly-supervised method for temporal action localization by maximizing the difference inside and outside the localization box.

ER: Early Recognition of Inattentive Driving Events Leveraging Audio Devices on Smartphones
Xiangyu Xu, Hang Gao, Jiadi Yu, Yingying Chen, Yanmin Zhu, Guangtao Xue, Minglu Li

We developed a audio-based early recognition system for inattentive driving events through Doppler effect.
