Research area: Computer Vision

I am a third year Phd student of Computer Science Department in University of British Columbia. My supervisor is Jim Little. I have studied in CAD&CG lab in Zhejiang University and the Centre for Vision Research in York University. I had an internship in Disney Research 2014, supervised by Dr. Peter Carr.

I use C++ for most part of my work based on OpenCV and VXL.

From September 2016, I organize Computer Vision Reading Group (cvrg) in UBC.
