Bio

‪Hang Dai‬ - ‪Google Scholar‬

Dr. Hang Dai is a Lecturer in Machine Learning at the School of Computing Science (IDA Section), University of Glasgow, Scotland, UK. He holds a Ph.D. in Computer Science from the University of York, where he built a 3D morphable model of human heads (LYHM) from the Headspace dataset. He was awarded a three-year full Oversea Research Scholarship from the University of York during his Ph.D. study.

He is a regular publisher in top AI/CV conferences like CVPR, ECCV, ICCV, ACM MM and etc. He also wins competitive top conference challenge awards, such as CVPR 2022 Waymo Autonomous Driving Challenge and ECCV 2020 Command for Autonomous Vehicles Challenge. He leads his research group to formulate the problem of highly accurate dichotomous image segmentation towards entering an era of demanding highly accurate outputs from AI algorithms to support delicate human-machine interaction and immersed virtual life and deliver the DIS benchmark to the community.
