PhD Candidate

School of Computer Science and Technology,
Tianjin University
Tianjin, China


I am currently a Ph.D. candidate in School of Computer Science and Technology, Tianjin University. My supervisor is Prof. Xiaochun CaoBefore that, I received the B.Eng degree from the School of Information Engineering, Hebei University of Technology, in 2010. And received the M.Eng degree from the School of Computer Science and  Communication Engineering, Tianjin University of Technology, in 2013, under the supervision of Prof. Yuanquan Wang.  

Currently, I'm a visiting Ph.D. student in Vision and Learning Lab at Electrical Engineering and Computer Science, University of California, Merced, working with Prof. Ming-Hsuan Yang.

My research interest includes computer vision and image processing.
