Yes! That is very scary! Just trying to stay positive and survive 🙈
Btw, NIH already was having a political appointee review all grants before NOA. This just solidifies the whole thing.

I was freaking out too. But read somewhere that the grant is technically awarded to an institution and not the PI. So hopefully it won’t come to that.

Why Fall colors in April? 🤣

Don’t joke this can be true! Like how they banned transgenic mice 🤦🏽‍♀️

Congratulations Andrew! This is amazing news! 🍾

We did found one! We say that these techniques can be used as data augmentation technique for creating ai models that can measure heart rate from videos, especially one with motion: motion-matters.github.io
Kind of surprising that these techniques do not destroy the heart rate of original video!

Neural Motion Transfer methods are used as a training data augmentation technique to improve machine learning models for camera physiological sensing.

This is awesome! Me and @silviasellan.bsky.social has recently started exploring how gender-agnostics 3D face models can help tracking faces during HRT and help in FFS, to realize this can also help in other facial reconstructive surgery and tracking weight gain-loss + aging.

Thats a great idea! We were also looking into other SLAM applications in robotics which also face the same challenge of textureless surface with dynamic lighting.

Our NFL-BA loss relies on the fact that points closer to the camera (depth map) with orientations facing the camera (normal map) reflect more light. NFL-BA loss is minimized during the Tracking & Mapping phase of existing SLAM frameworks, results shown on 3DGS SLAMs.

Actually in 2.5yrs that’s my biggest green flag - passion!

I know 🤣

Why this bias against cats? 😭
Funny cat pics = huge mental health boost! 🤣

This is my first time and I am surprised to see how good the recommendations were and what a good quality of reviewers we have in the pool!

A few key insights:

❌ CtrlNet struggles to preserve input color & texture during relighting.
✅ Albedo-cond. Stable Diffusion to the rescue.

❌ Only scribble input in CtrlNet doesn't work at all.
✅ Use latent code from a denoising autoencoder that predicts shading map from scribble+normal map.
