Strong performance on clean benchmarks is not enough. Vision systems must also survive blur, noise, compression, weather, and other real-world shifts. Introducing RoCo-Spring, an official @NeurIPSConf 2026 Competition Track challenge on robust dense correspondence. Compete in: Optical Flow | Stereo Matching | Scene Flow | Exploration We have made participation easy: register your team, download the data, clone the PTLFlow-based starter devkit, run the pipelines, and submit. 🌐 roco-spring.github.io/ 💻 github.com/hmorimitsu/roco-s… Questions? [email protected] or DM me. #NeurIPS2026 #ComputerVision #Robustness Organizers: @shashankska, @JennySchmalfuss, Victor Oei, Katrin Bauer, Henrique Morimitsu, Andres Bruhn, @margret_keuper Affiliations: @dwsunima, @nvidia, @cvml_mpiinf, @Uni_Stuttgart, and University of Science and Technology Beijing.

I spy with my little eye... a WACV paper. We investigate visual frame detection using Minimum Cost Multicut clustering. Check out the paper to see which foundation model embedding space works best: arxiv.org/pdf/2412.01296 @IsaacBr45419303 @margret_keuper @SteWalter @dwsunima
