About

I am currently a postdoctoral researcher at Tongji University, jointly supervised by Prof. Guang Chen and Prof. Changjun Jiang. I earned my Ph.D. from Tongji University in 2024.

My research focuses on transfer learning and its applications in Embodied AI and AI4Science. I am particularly interested in developing robust and efficient algorithms for transfer learning and their applications in computer vision, robotics, and drug discovery.

RCP-Bench

RCP-Bench: Benchmarking Robustness for Collaborative Perception Under Diverse Corruptions

Shihang Du, Sanqing Qu, Tianghang Wang, Xudong Zhang, Yunwei Zhu, Jian Mao, Fan Lu, Qiao Lin, Guang Chen
CVPR IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), 2025

We introduce RCP-Bench, the first comprehensive benchmark designed to evaluate the robustness of collaborative detection models under a wide range of real-world corruptions. RCPBench includes three new datasets (i.e., OPV2V-C, V2XSet-C, and DAIR-V2X-C) that simulate six collaborative cases and 14 types of camera corruption resulting from external environmental factors, sensor failures, and temporal misalignments.

BMD-v2

General Class-Balanced Multicentric Dynamic Prototype Pseudo-Labeling for Source-Free Domain Adaptation

IJCV International Journal of Computer Vision (IJCV), 2025

We promote the vanilla BMD to BMD-v2 by incorporating a consistency-guided reweighting strategy to improve inter-class balanced sampling, and leveraging the silhouettes metric to realize adaptive intra-class multicentric clustering.

GLC++

GLC++: Source-Free Universal Domain Adaptation through Global-Local Clustering and Contrastive Affinity Learning

Sanqing Qu, Tianpei Zou, Florian Röhrbein, Cewu Lu, Guang Chen, Dacheng Tao, Changjun Jiang
arXiv arXiv Preprint, 2024

Despite the simple global and local clustering (GLC) technique achieving commendable performance in separating "known" and "unknown" data, its reliance on pseudo-labeling supervision limits its capacity to discriminate among different "unknown" categories. To alleviate this, we promote GLC to GLC++ by developing a new contrastive affinity learning strategy.

HGL

HGL: Hierarchical Geometry Learning for Test-time Adaptation in 3D Point Cloud Segmentation

Tianpei Zou*, Sanqing Qu*, Zhijun Li, Alois Knoll, Lianghua He, Guang Chen, Changjun Jiang
ECCV European Conference on Computer Vision (ECCV), 2024

In this paper, we delve into TTA in 3D point cloud segmentation and propose a novel Hierarchical Geometry Learning (HGL) framework. HGL comprises three complementary modules from local, global to temporal learning in a bottom-up manner.

LEAD

LEAD: Learning Decomposition for Source-free Universal Domain Adaptation

Sanqing Qu, Tianpei Zou, Lianghua He, Florian Röhrbein, Alois Knoll, Guang Chen, Changjun Jiang
CVPR IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), 2024

For Universal Domain Adaptation (UniDA), in this paper, we propose a new idea of LEArning Decomposition (LEAD), which decouples features into source-known and -unknown components to identify target-private data.

MAP

MAP: MAsk-Pruning for Source-Free Model Intellectual Property Protection

Boyang Peng*, Sanqing Qu*, Yong Wu, Tianpei Zou, Lianghua He, Alois Knoll, Guang Chen, Changjun Jiang
CVPR IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), 2024

In this paper, we target a practical setting in IP protection, i.e., Source-free Model IP protection. To achieve this, we propose a novel MAsk Pruning (MAP) framework.

GLC

Upcycling Models under Domain and Category Shift

Sanqing Qu*, Tianpei Zou*, Florian Röhrbein, Cewu Lu, Guang Chen, Dacheng Tao, Changjun Jiang
CVPR IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), 2023

In this paper, we explore the Source-free Universal Domain Adaptation (SF-UniDA). SF-UniDA is appealing in view that universal model adaptation can be resolved only on the basis of a standard pre-trained closed-set model.

MAD

Modality-Agnostic Debiasing for Single Domain Generalization

Sanqing Qu, Yingwei Pan, Guang Chen, Ting Yao, Changjun Jiang, Tao Mei
CVPR IEEE/CVF Computer Vision and Pattern Recognition Conference (CVPR), 2023

Existing single-DG techniques commonly devise various data-augmentation algorithms. In contrast, we target a versatile Modality-Agnostic Debiasing (MAD) framework for single-DG, that enables generalization for different modalities.

EFall

Neuromorphic Vision-based Fall Localization in Event Streams with Temporal–spatial Attention Weighted Network

Guang Chen*, Sanqing Qu*, Zhijun Li, Haitao Zhu, Jiaxuan Dong, Min Liu, Jorg Conradt
T-CYB IEEE Transactions on Cybernetics (T-CYB), 2022

In this paper, we proposed a bio-inspired event-camera based falls temporal localization framework. Specifically, we propose a event density-based action proposal generation scheme, and introduce a temporal-spatial attention mechanism for action modeling.

ACM-Net

ACM-Net: Action Context Modeling Network for Weakly-supervised Temporal Action Localization

Sanqing Qu, Guang Chen, Zhijun Li, Lijun Zhang, Fan Lu, Alois Knoll
arXiv arXiv Preprint, 2021

In this paper, we propose an action-context modeling network termed ACM-Net, which integrates a three-branch attention module to measure the likelihood of each temporal point being action instance, context, or non-action background, simultaneously.
