I'm a Ph.D student of Baek's Group at Computer Graphics Lab @ POSTECH, advised by Prof. Seung-Hwan Baek. My research interests are 3D reconstruction and inverse rendering. I work as a visiting researcher at University of Toronto, advised by Prof. David B. Lindell.

Publications

A Real-world Display Inverse Rendering Dataset

Seokjun Choi, Hoon-Gyu Chung, Yujin Jeon, Giljoo Nam, Seung-Hwan Baek

ICCV 2025

[PDF] [arXiv] [Project] [Code] [Video]

We present the first real-world dataset for display-based inverse rendering, captured using a calibrated LCD display and stereo polarization cameras under OLAT patterns.

Differentiable Inverse rendering with Interpretable Basis BRDFs

Hoon-Gyu Chung, Seokjun Choi, Seung-Hwan Baek

CVPR 2025

[PDF] [arXiv] [Project] [Code] [Video]

We introduce a differentiable inverse rendering method that produces interpretable basis BRDFs . It supports physically-based novel-view relighting and intuitive scene editing.

Differentiable Point-based Inverse Rendering

Hoon-Gyu Chung, Seokjun Choi, Seung-Hwan Baek

CVPR 2024

[PDF] [arXiv] [Project] [Code] [Video]

We present differentiable point-based inverse rendering, DPIR, an analysis-by-synthesis method that processes images captured under diverse illuminations to estimate shape and spatially-varing BRDF.
