🚨New doctor in the house!🚨
Congrats to @timdarcet.bsky.social for his tremendous work (DINOv2, registers, CAPI) & successful PhD defense followed by ~2 hrs of questions -- he's got stamina!
Congrats to his incredible team of advisors from Inria & Meta: @jmairal.bsky.social, P. Bojanowski, M. Oquab

PanSt3R: Multi-view Consistent Panoptic Segmentation

Lojze Zust, Yohann Cabon, Juliette Marrie, Leonid Antsfeld, Boris Chidlovskii, Jerome Revaud, @gabrielacsurka.bsky.social

tl;dr: MUSt3R-> Mask2Former with joint queries -> 3DGS + tricks = panoptic profit

The PAISS summer school is back with an incredible line of speakers (and more to come). Spread the word !

My experiments are run on a 48GB GPU. A 24GB GPU may be sufficient depending on the application. Feel free to reach out if you have any questions or run into any issues, and we can find a way to make it work within your memory constraints.

Thanks! So far, I have been evaluating on standard datasets for foreground/background segmentation (SPIn-NeRF, NVOS) and open-vocabulary object localization (LERF). The object removal task you introduce in Semantics-Controlled GS could be another interesting application!

Uplifting is implemented in the forward rendering process, so it is as fast as forward rendering. Experimentally, it takes around 2ms per image per feature dimension. For example, uplifting 100 DINOv2 feature maps of dimension 40 (PCA-reduced) takes about 9s. See Appendix B.1 for more details.

(3/3) LUDVIG uses a graph diffusion mechanism to refine 3D features, such as coarse segmentation masks, by leveraging 3D scene geometry and pairwise similarities induced by DINOv2.

Illustration of the inverse and forward rendering of 2D visual features produced by DINOv2.

(2/3) We propose a simple, parameter-free aggregation mechanism, based on alpha-weighted multi-view blending of 2D pixel features in the forward rendering process.

(1/3) Happy to share LUDVIG: Learning-free Uplifting of 2D Visual features to Gaussian Splatting scenes, that uplifts visual features from models such as DINOv2 (left) & CLIP (mid) to 3DGS scenes. Joint work w. @dlarlus.bsky.social @jmairal.bsky.social
