Can we estimate relative rotations between *non-overlapping* images? Yes! Our new #CVPR2021 paper uses 4D correlation volumes to reason about implicit cues that reveal their geometric relationship. With Bharath Hariharan Noah Snavely @elorhadar. Project page: ruojincai.github.io/ExtremeRotatio…

Introducing MegaScenes—a scene-level dataset containing 100K SfM reconstructions and 2M images with open content licenses. We validate its effectiveness in training large-scale, generalizable models on the task of novel view synthesis. 1/N project page: megascenes.github.io

Extreme Rotation Estimation in the Wild Hana Bezalel, Dotan Ankri, Ruojin Cai Hadar Averbuch-Elor tl;dr: MegaDepth/Scenes subset with small/large/no overlap image pairs, the task is R prediction arxiv.org/abs/2411.07096

Doppelgangers++: Improved Visual Disambiguation with Geometric 3D Features Yuanbo Xiangli, Ruojin Cai, Hanyu Chen, Jeffrey Byrne, Noah Snavely tl;dr: new dataset (55K pairs) + Mast3r == PROFIT arxiv.org/abs/2412.05826

Introducing Doppelgangers++! 🚀 An enhanced pairwise image classifier that tackles visual aliasing (doppelgangers) to improve 3D reconstruction accuracy across diverse, real-world scenes. 🌍✨ 🔗Project page: bit.ly/3VAPMJc. Code is also available.
