Zhenyang Li (李镇洋)

23 Fall PhD postgraduate

I am currently a Ph.D. student (since Fall 2023) in the Department of Electrical and Electronic Engineering at The University of Hong Kong (HKU).

Prior to joining HKU, I received my M.S. degree in Big Data Engineering from the Department of Automation and Shenzhen International Graduate School at Tsinghua University (THU), and my B.S. degree in Electronic and Information Engineering from Nanjing University of Science and Technology (NJUST).

I am fortunate to be under the guidance of Dr. Yifan (Evan) Peng from the WeLightLab@HKU in the EEE&CS department at HKU and advised by Prof. Kai Zhang from the Intelligent Transportation Joint Laboratory at Tsinghua University.

My research interests encompass Computer Vision (3D/4D), Computer Graphics (Rendering), VR/AR/MR, and Holographic Imaging/Display.

📊 Research Impact:

🔬 Research Focus

My research interests lie at the intersection of Computer Vision, Computer Graphics, and Artificial Intelligence. I focus on enabling machines to perceive, understand, and generate photorealistic 3D/4D visual content. Specifically, my work concentrates on the following areas:

🎨 3D/4D Reconstruction & Generation

  • Neural Representations: Neural Radiance Fields (NeRF) and 3D Gaussian Splatting for high-fidelity scene modeling
  • Dynamic Scenes: 4D reconstruction with enhanced velocity field modeling for video sequences
  • Physics-based Generation: Material-agnostic system identification and physically correct video synthesis
  • Event-based Vision: Event camera rendering and dynamic scene reconstruction using event streams

🤖 Vision-Language & Multimodal AI

  • Visual-Language-Action Models: Embodied AI for robotics and interactive systems
  • Video Understanding: Temporal modeling and action recognition in dynamic scenes
  • Cross-modal Learning: Bridging vision, language, and action spaces

🖼️ Computational Imaging & Holography

  • Holographic Display: Computer-generated holography with camera-calibrated neural networks
  • 3D Imaging: Multi-view stereo, depth estimation, and 3D scene understanding
  • Feature Matching: Overlapping region-based techniques for robust image correspondence
