Interested in Visual Place Recognition

😀 About me

I am a PhD student at the University of Macau, supervised by Prof. Chi-Man Pun and Prof. Qieshi Zhang. Prior to this, I earned my Master’s degree from Shenzhen Institute of Advanced Technology (SIAT), Chinese Academy of Sciences.

My research is at the intersection of Computer Vision and Robotics, with a core focus on Visual Place Recognition (VPR). Now, I am particularly interested in developing robust, lightweight methods for autonomous navigation.

🔍 Research Interests

  • Visual Place Recognition (VPR): Lightweight feature extraction and distilled representation for large-scale scene recognition.
  • Generative Features for VPR: (Ongoing) Exploring Diffusion-based descriptors (DIFT) for localization tasks.
