I have finished my thesis on August 2018.
I have been a Phd student of Computer Science Department in University of British Columbia since 2014 September. 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, VXL, and VLFeat. 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.
