Research Interest

My research interests mainly focus on developing novel models and algorithms to address practical challenges in deploying artificial intelligence systems to various real-world application domains. I am currently engaged in the following topics:

Visual correspondence: wide-baseline matching, semantic matching, camera pose estimation, novel-view synthesis, 3D symmetry, 3D reconstruction, point cloud registration, text-to-3D generation, 3D multimodal LLMs, and foundation models for 3D vision.
Representation learning: equivariant representation learning, self-supervised learning, multi-modal learning, geometric deep learning, and diffusion models for visual tasks.

The application domains of interest include, but are not limited to, visual geometry/3D vision (e.g., autonomous driving, visual SLAM, and multi-view geometry), computational photography (e.g., image restoration and enhancement, burst photography in the dark, and camera ISP), and AR/VR technologies (e.g., eye tracking, gaze estimation, pose estimation, and neural rendering).
