Hi, Iβm Zongqi He. I received my Bachelorβs degree from the Department of Electrical and Electronic Engineering at The Hong Kong Polytechnic University. I was very fortunate to be advised by Prof. Kenneth K. M. Lam during my undergraduate studies. I am now a Ph.D. student at The University of Hong Kong, advised by Yifan (Evan) Peng.
My research interests include computer vision, deep learning, low-level vision, and 3D/4D reconstruction.
