Charig Yang

I am a fourth (final) year PhD student at the Visual Geometry Group (VGG) at University of Oxford, advised by Andrew Zisserman and Weidi Xie. I am also interning at Meta from June to December 2024, and am expected to graduate by April 2025.

I am also part of Autonomous Intelligent Machines and Systems at University of Oxford, and am generously funded by EPSRC and AIMS.

I did my undergraduate in Engineering Science, also at Oxford. During which, I spent lovely summers at Japan Railways, Metaswitch, True, CP Group, and Oxford’s Engineering Department.

Prior to which, I was born and raised in the suburbs of Bangkok, Thailand.

Research

My PhD research explores novel methods in learning and using temporal signals in videos. I am particularly interested in: video understanding, self-supervised learning, segmentation, and new applications.

Shuffling and ordering sequences reveals changes that are monotonic over time

Moving Object Segmentation: All You Need Is SAM (and Flow)

SAM + Optical Flow = FlowSAM

It's About Time: Analog Clock Reading in the Wild
Charig Yang, Weidi Xie, Andrew Zisserman
CVPR, 2022
project page / arXiv

We show that neural networks can read analog clocks without manual supervision.

Self-supervised Video Object Segmentation by Motion Grouping
Charig Yang, Hala Lamdouar, Erika Lu, Andrew Zisserman, Weidi Xie
Short: CVPR Workshop on Robust Video Scene Understanding, 2021 (Best Paper Award)
Full: ICCV, 2021

We use transformers to group independently moving parts into layers, resulting in self-supervised segmentation.

Betrayed by Motion: Camouflaged Object Discovery via Motion Segmentation
Hala Lamdouar, Charig Yang, Weidi Xie, Andrew Zisserman
ACCV, 2020
project page / arXiv

We consider the task of camouflaged animal discovery and present a large-scale video camouflage dataset.
