Associate Professor
Beijing University of Posts and Telecommunications, Beijing, Chinaqiyg AT bupt DOT edu DOT cn
I am currently an associate professor at BUPT. Previously, I was a PhD student at Pattern Recognition and Intelligent Systems (PRIS) laboratory at BUPT. I received the PhD in Signal Processing from Beijing University of Posts and Telecommunications (BUPT) in 2015 (Supervisor: Professor Jun Guo). From 2019 to 2020, I was a visiting scholar at SketchX lab headed by Dr. Yi-Zhe Song at the Centre for Vision Speech and Signal Processing (CVSSP) in University of Surrey. I also worked as a guest PhD at Aalborg University in Denmark in 2013 and a visiting researcher at Sun Yat-sen University in China in 2014.
My research interests include perceptual grouping, and sketch-based machine vision algorithms and tasks, such as sketch-based image retrieval (SBIR), sketch recognition, sketch synthesis and sketch-based visual understanding.
