Qingnan Fan

I am a PhD student in the Computer Science and Technology School of Shandong University since 2014. I am supervised by Prof. Baoquan Chen.

I visited Tel Aviv University, Hebrew University of Jerusalem several times between 2014 to 2015 to work with Prof. Daniel Cohen-Or and Prof. Dani Lischinski.

I was a research intern in the Visual Computing Group of MSRA supervised by David Wipf between Sept. 2016 to Feb. 2018. I also collaborated with Xin Tong, Gang Hua and Jiaolong Yang while in MSR.

I was a research intern in the Advanced Innovation Center for Future Visual Entertainment led by Prof. Baoquan Chen, in Beijing Film Academy between Mar. to Jul. in 2018.

Currently I'm a visiting student in Cambridge Image Analysis (CIA) group led by Carola-Bibiane Schönlieb at the Department of Applied Mathematics and Theoretical Physics (DAMTP), Cambridge University.

My research interest mainly lies in computer vision, image processing, video processing, computational photography. I'm specifically interested in interactive real-time video segmentation, reflection removal, image smoothing, intrinsic image decomposition, and practical application of my developed techniques on mobile devices.

Image Smoothing via Unsupervised Learning
Qingnan Fan, Jiaolong Yang, David Wipf, Baoquan Chen, Xin Tong.
SIGGRAPH Asia, 2018
arXiv / codes / supp file / bibtex

Treat deep learning as an optimization tool to minimize the proposed image smoothing objective function in an unsupervised manner. Multiple different smoothing effects can be easily learned by adaptively changing the proposed objective function.

Decouple Learning for Parameterized Image Operators
Qingnan Fan*, Dongdong Chen*, Lu Yuan, Gang Hua, Nenghai Yu, Baoquan Chen.
ECCV , 2018
arXiv / codes / supp file / poster / bibtex

The first decouple learning framework that is capable of successfully incorporating many different parameterized image operators into a single network without requirement of retraining or fintuning any other networks.

Revisiting Deep Intrinsic Image Decompositions
Qingnan Fan, Jiaolong Yang, Gang Hua, Baoquan Chen, David Wipf.
CVPR , 2018 (Oral)
arXiv / codes / slides / supp file / poster / presentation (start from 36:44) / bibtex

The first demonstration of a single basic deep architecture capable of achieving state-of-the-art results when applied to each of the major intrinsic benchmarks.

A Generic Deep Architecture for Single Image Reflection Removal and Image Smoothing
Qingnan Fan, Jiaolong Yang, Gang Hua, Baoquan Chen, David Wipf.
ICCV, 2017
arXiv / codes / supp file / poster / bibtex

An advanced deep architecture for low-level vision tasks; A novel reflection image synthesis approach which enables outstanding generalization ability to real images with trained newtork.

JumpCut: Non-Successive Mask Transfer and Interpolation for Video Cutout
Qingnan Fan, Fan Zhong, Dani Lischinski, Daniel Cohen-Or, Baoquan Chen.
SIGGRAPH Asia, 2015
codes / slides / video / supp file / dataset / bibtex

An interactive real-time video segmentation algorithm. Significantly improve the video cutout accuracy and efficiency.
