Ho Kei (Rex) Cheng
I am currently a Ph.D. candidate at the University of Illinois Urbana-Champaign, advised by Alexander Schwing .
Before that, I was at The Hong Kong University of Science and Technology, advised by Yu-Wing Tai and Chi Keung Tang .
I am recently working on scalable video understanding, including video object segmentation and open-world object tracking.
I am delighted to have worked closely with Seoung Wug Oh , Brian Price , and Joon-Young Lee at Adobe Research in 2022.
Looking for student collaborators in video segmentation. Feel free to contact me.
Research (hover over videos to play):
arXiv 2023
Equipped with an object transformer that integrates pixel-level features and object-level features for efficient and robust video object segmentation in challenging scenarios.
ICCV 2023
Open-world video segmentation achieved by combining universal image segmentation with temporal propagation. Easy to extend.
ECCV 2022
We look at video object segmentation from a memory perspective and design a pipeline that models both short-term and long-term dependencies effectively.
Used by supervisely and Track-Anything.
CVPR 2021
We decouple the problem of interactive video segmentation into single-frame interaction and temporal propagation, showing that this works better by a large margin.
Used by Sieve.
CVPR 2020
We train an iterative refinement network that generalizes to high-quality/high-resolution (4K+) segmentation with just low-resolution (<500 pixels per side) data.
Misc:
- I was a proud member of the HKUST Robotics Team. A short clip.
-
I am generally interested in artificial intelligence. I believe in AGIs and has high hope for their potential to transform human civilization for the better.
- I like this quote from Sartre: "Man is condemned to be free. Condemned, because he did not create himself, in other respect is free; because, once thrown into the world, he is responsible for everything he does."
- Look at this cat in HKUST. Another picture. Or this cat.
- "Ho Kei" (with the space) is my first name and "Cheng" is my last name. "Rex" is the commonly used "english name" that is not part of my legal name.
