3D Computer Vision / Pose and Mesh Reconstruction

Jeongwan On

I am a combined MS/PhD student at the Artificial Intelligence Graduate School (AIGS), UNIST, and a member of the UNIST Vision and Learning Lab (UVLL), advised by Prof. Seungryul Baek. I received my B.S. degree in Statistics from Chonnam National University.

My research focuses on 3D human and hand-object reconstruction from monocular videos, with broader interests in multi-person tracking, 3D computer vision, and human-object interaction.
