SOTA virtual face re-aging techniques often struggle to preserve identity for large age changes.
We present MyTimeMachine, a personalized virtual aging gen. model, trained with ~50 images across 20-40 years.

Fueling up for #ICCV2025 deadline with some local Pizza!
PS. I kind of like hanging around in the lab on the deadline day! So much energy all around!

Paper rejected from #CVPR2025, paper ready for #ICCV2025 💪

My students will present two papers, including one oral paper, in #WACV2025, which centers on personalized generative face models.
Thanks @luchaoqi.bsky.social for leading this direction.
Unfortunately, couldn't attend WACV as my other students needed me for MICCAI and ICCV deadlines!

I don’t know how this will be implemented, but may be time to search for opportunities outside the US!
THEY'RE GOING TO ISSUE PERMANENT VISA BANS TO TRANS VISITORS TO THE US.

This isn't just for athletes. The directive as stated applies to all visa applications made by trans folks and declare it material fraud to use a different gender marker on applications.

Exclusive: State department memo directs officers to bar those deemed to misrepresent birth sex on applications

X is like this cringy Desi TV show, that you hate but continue watching … where I saw how trans hatred changed to Indians in tech hatred in matter of days - not sure how to feel about that! 😒
this website is like the suburbs. it's pleasant, but dull

the other website is like the big city with a terrible mayor. a lot happens there, even things you may not like

SLAM algorithms struggle on endoscopy videos - specularity, textureless, & dynamic lighting.

We introduce a Near-Field Light Bundle Adjst. loss (NFL-BA): improves performance of SOTA SLAM, e.g. MonoGS (⬆️35% in tracking, ⬆️48% in mapping).

See asdunnbe.github.io/NFL-BA/

Its almost time to recruit PhD students, any advice on how people identify the best students for their labs? This feels like the hardest and possibly the most consequential decision I have to make (so far I have been reasonably lucky). What qualities do you look for and any red flags to watch out?

💡Introducing ScribbleLight, a generative model that can relight an image with simple scribbles - making it easier for virtual staging and interior design of homes.

Led by Jun-Myeong, collabs with Anand (TTIC), Pieter (W&M), and Annie.

Holiday party with the UNC Vision & Graphics Lab students … where they get to see more relaxed version of me after the CVPR deadline! 🤣
