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.
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.
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.
We train an iterative refinement network that generalizes to high-quality/high-resolution (4K+) segmentation with just low-resolution (<500 pixels per side) data.
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."
