Hi there, I am Fan Li (李帆), a Ph.D. candidate at the School of Artificial Intelligence (formerly the Unmanned System Research Institute), Northwestern Polytechnical University (NPU). My research focuses on the intersection of unmanned systems and computer vision, dedicated to overcoming key visual perception bottlenecks faced by intelligent unmanned platforms operating in real-world, complex, and dynamic environments.

Specifically, my research interests include:

  • Generative-driven next-generation perception paradigms

  • Generalization of unmanned systems’ perception in complex and dynamic environments

  • Robust visual understanding in open-world scenarios

  • Multi-modal 3D scene understanding and representation learning

My research aims to enable resilient and trustworthy visual perception and scene understanding for unmanned systems operating in complex, dynamic, and uncertain environments. This work strives to significantly expand the operational envelope of unmanned systems, facilitating their scaling from controlled testbeds to unstructured and real-world scenarios.

I am always open to collaborations and interdisciplinary discussions. If you are interested in exploring potential research avenues or discussing related topics, please contact me at lifan.messages@gmail.com.

Better to Teach than to Give: Domain Generalized Semantic Segmentation via Agent Queries with Diffusion Model Guidance

Fan Li, Xuan Wang, Min Qi, Zhaoxiang Zhang, Yuelei Xu

Accepted at ICML 2025 (Spotlight💡)

Project

  • Developed an agent-query–driven framework for domain-generalized semantic segmentation, in which learnable agent queries act as an interface to inject diffusion-model priors into visual perception networks, thereby improving cross-domain generalization.

Images as Noisy Labels: Unleashing the Potential of the Diffusion Model for Open-Vocabulary Semantic Segmentation

Fan Li, Xuanbin Wang, Xuan Wang, Zhaoxiang Zhang, Yuelei Xu

Accepted at ICCV 2025 (Highlight💡)

Project

  • Developed the first denoising-based learning framework for visual perception, which treats images as noisy labels and acquires semantic knowledge during the iterative denoising process of diffusion models, thereby enhancing fine-grained scene understanding in open-world scenarios for vision–language models.

No Object Is an Island: Enhancing 3D Semantic Segmentation Generalization with Diffusion Models

Fan Li, Xuan Wang, Xuanbin Wang, Zhaoxiang Zhang, Yuelei Xu

Accepted at NeurIPS 2025 Main Track

Project

  • Developed the first diffusion-based cross-domain 3D semantic segmentation framework, leveraging pretrained 2D image diffusion priors to guide 3D models in establishing semantic dependencies among point-cloud instances, thereby enabling cross-modal semantic enhancement and enriching point-cloud representations.
  • Unlocking Instance Semantic Awareness for Domain Adaptive Semantic Segmentation. Fan Li, Xuan Wang, Min Qi, Zhaoxiang Zhang, Chengming Xu, Yuelei Xu. ICME 2025
