Hi there 👋 I am Shuang Li!

I am a Ph.D. student in the Smart Mind and Super Vision Group at Chongqing University of Posts and Telecommunications, advised by Prof. Xinbo Gao and Prof. Jiaxu Leng.

My research focuses on human-centered trustworthy video surveillance systems, especially person re-identification, visible-infrared perception, face super-resolution, and small object detection. Before my Ph.D. study, I received my M.Eng. from Kunming University of Science and Technology under the supervision of Prof. Huafeng Li. Earlier, I earned my B.Eng. from Chongqing University of Posts and Telecommunications, advised by Associate Prof. Linghui Liu and Prof. Xiao Luan.
