Jinwei Gu
Assistant Professor
My research interests are computational imaging, computer vision and computer
graphics. I am particularly interested in understanding and modeling the physics-based image
formation mechanism and the intrinsic structure of the visual
appearance of various types of natural phenomena,
and applying them in:
Computational Photography for capturing
high-quality, information-rich photographs and videos;
Physics-based Computer Vision for recovering higher-level
information such as geometry, material
properties, and illumination;
Data-Driven Computer Graphics for
acquiring and recreating realistic visual appearance
of natural phenomena.
