Biography

Xiaowei Hu received his Ph.D. degree in Computer Science and Engineering from The Chinese University of Hong Kong (CUHK) in 2020, supervised by Prof. Pheng-Ann Heng and Prof. Chi-Wing Fu. Before that, he received the B. Eng. degree in Computer Science and Technology from South China University of Technology (SCUT) in 2016, under the supervision of Prof. Xuemiao Xu. He is currently working as a postdoctoral fellow in the Chinese University of Hong Kong.

His research interests cover computer vision and deep learning, with special emphasis on low-level vision. Specifically, he is dedicated to designing learning frameworks by exploring the physical properties of various vision applications, including shadow image analysis, rain removal, and saliency detection. He is also interested in exploring robust learning algorithms with less human supervision for image recognition and restoration, which helps to improve scene understanding and enhance camera capability.
