I have obtained my Ph.D. degree at HKUST, advised by Prof.
Pedro Sander. During the Spring 2019,
I was a visiting student to the University of California, San Diego, supervised by Prof.
Hao Su. For the autumn 2017, I was a
research intern at SenseTime, supervised by Dr.
Qiong Yan. Before that, I received my
B.S. degree in EE department from Tongji University in 2013.
Since April 2020, I have started at SULab as a postdoctoral researcher, working with Prof. Hao Su.
My research interest includes computer graphics and computer vision, especially in 3D geometry processing, 3D reconstruction. My work covers efficient rendering, multi-view reconstruction, portrait relighting and virtual reality.

[project (code)] [paper]
This is an extension of our ICCV work (Point-based Multi-view Stereo Network). In this paper, we introduce visibility-aware multi-view feature aggregation modules to gather information from visible views only for better depth prediction accuracy.

[project (code)] [paper] [video]
An iterative framework to predict the depth of a scene using point cloud representation from multiple views. Use deep learning over the kNN graph to predict the residual for geometry estimation refinement.
