Jianrui Cai

I did my PhD at the Department of Computing, The Hong Kong Polytechnic University, where I was advised by Prof. Lei Zhang. I did my BSc and MSc at the College of Computer Science and Electronic Engineering, Hunan University.

I had worked as a research intern at DJI (Shenzhen, China), Google (Seattle, WA, US) and Apple (Cupertino, CA, US).

Research

I am interested in Image Processing, Computational Photography and Computer Vision.
Much of my research is about Deep Learning and Camera Pipeline.
(Image Restoration, Image Enhancement, Color Mapping and Image Compression)
