Yixuan Li (李奕萱)

I am currently a second-year Ph.D. student at MMLab in Department of Information Engineering, CUHK, advised by Prof. Dahua Lin. Before that, I received my Master's degree from Nanjing University in 2022, supervised by Prof. Limin Wang, and my Bachelor's degree also from Nanjing University in 2019.

My research area is 3D vision, especially 3D scene reconstruction and generation, with a recent focus on neural rendering for large-scale scenes. My previous research interest was video understanding and spatial-temporal action detection.

PACER+: On-Demand Pedestrian Animation Controller in Driving Scenarios
Jingbo Wang, Zhengyi Luo, Ye Yuan, Yixuan Li, Bo Dai.
CVPR, 2024
code

We could generate human motion interactions with spatially controllable MDM that is only trained on single-person data.
InterControl: Generate Human Motion Interactions by Controlling Every Joint

Arxiv, 2023
arXiv / code

We could generate human motion interactions with spatially controllable MDM that is only trained on single-person data.
MatrixCity: A Large-scale City Dataset for City-scale Neural Rendering and Beyond
Yixuan Li*, Lihan Jiang*, Linning Xu,Yuanbo Xiangli, Zhenzhi Wang, Dahua Lin, Bo Dai.
ICCV, 2023
paper / project page / code

A large scale synthetic dataset from Unreal Engine 5 for city-scale NeRF rendering.

Sparse Action Tube Detection
Yixuan Li*, Zhenzhi Wang*, Zhifeng Li, Limin Wang.
TIP, 2024
paper

We present a simple end-to-end action tube detection method, which reduces the dense hand-crafted anchors, captures longer temporal information and explictly predicts the action boundary.

MultiSports: A Multi-Person Video Dataset of Spatio-Temporally Localized Sports Actions
Yixuan Li, Lei Chen, Runyu He, Zhenzhi Wang, Gangshan Wu, Limin Wang.
ICCV, 2021
one track of ICCV2021, ECCV2022 Workshop DeeperAction.
paper / code

A fine-grained and large-scale spatial-temporal action detection dataset with 4 different sports, 66 action categories.
Actions as Moving Points
Yixuan Li*, Zixu Wang*, Limin Wang, Gangshan Wu.
ECCV, 2020
paper / code

A conceptually simple, computationally efficient, and more precise anchor-free action tubelet detector.
