Yicun Liu

I am an M.S. student in Computer Science at Columbia University, currently working with Prof. John R. Kender on video and text understanding. Before that, I received my B.Eng degree from The Chinese University of Hong Kong, where I was fortunate to work with Prof. Loy Change Chen.

I interned at: Yahoo! Paranoids on data and security infrastructure / SenseTime Research on computer vision and machine learning research.

Visually Imbalanced Stereo Matching
Yicun Liu, Jimmy Ren, Jiawei Zhang, Jianbo Liu, Mude Lin
In Submission, 2019

Resemble to the human visual system (HVS), stereo machines collapse under imbalanced stereo inputs. We show that guided by the rough object contour, the corrupted view can be restored, and stereopsis can be regenerated.

By exploiting the properties of the gradient domain, we establish a selfie-friendly stylization framework that preserved natural skin color and facial structure.

Improving Mobile Phone's Image Quality by Deep Learning
Cen Huang*, Yicun Liu*, supervised by Prof. Loy Change Chen

Final Year Thesis (Undergraduate), 2018
pdf / slides

We bridge the gap of image quality in mobile phones and DSLRs by designing a multi-domain image translation framework, which learns the comprehensive enhancement transformation from heterogeneous real-world datasets.
