Interested in doing research in 3D computer vision, geometry and machine learning? Open PhD position available in my group. Check out vlarsson.github.io/positions/ for more details on how to apply. Application deadline June 17th! Feel free to contact me if you have any questions.

Colmap 3.11 release,a LOT of of cool things: - incremental mapper with absolute pose priors - CUDA-based BA through Ceres (disabled by default). - PoseLib's RANSACs - New BA covariance estimation,faster & more robust than Ceres. - Fix Affine-covariant SIFT github.com/colmap/colmap/…

Introducing GeoCalib for camera calibration: gravity & intrinsics from a single image 📸 ➡️Differentiable geometry optimization FTW! ➡️Video youtu.be/uOmTwvKreM4 ➡️Demo veichta-geocalib.hf.space ➡️Paper arxiv.org/pdf/2409.06704 by @veichta with @PhilippCSE @mapo1 for #ECCV2024 1/

@Parskatt @abcamiletto @Hydra Yes since hydra is based on omegaconf so they work very well together. I’ve started with omegaconf only so some command line parsing is a bit cluttered but otherwise it works very well.

@veichta @abcamiletto @Hydra Wait, you have both hydra and omegaconf?

IMO a problem in many ML codebases is that there is no single place for all hparams. Hoping to make some code where this is possible.

@Parskatt @abcamiletto @Hydra I’ve used hydra in GeoCalib and was quite happy with it :) it’s not perfect but if you want everything in a single place, it is not a bad option.

@abcamiletto @Hydra @abcamiletto do you have a good example of hydra in a cv codebase (e.g. your own?). I would like to see a non-cluttered example.
