Jianrui Cai

I am a Ph.D. student in Department of Computing (COMP), The Hong Kong Polytechnic University, under the supervision of Prof. Lei Zhang.

Previously, I received my B.Sc. and M.Sc. from College of Computer Science and Electronic Engineering, Hunan University, in 2012 and 2015, respectively.
During my Ph.D. period, I was a Research Intern in the Camera team at DJI Innovations (Shenzhen, China) from Jun 2016 to Jan 2019. I will also join Google (Seattle, WA, USA) as an Intern in Aug 2019.

I'm interested in Image Processing, Computational Photography and Computer Vision.
Much of my research is about Deep Learning and Camera Pipeline.
