DeDoDe 🎶 Detect, Don't Describe - Describe, Don't Detect, for Local Feature Matching
The DeDoDe detector learns to detect 3D consistent repeatable keypoints, which the DeDoDe descriptor learns to match. The result is a powerful decoupled local feature matcher.
Training DeDoDe
DISCLAMER: I've (Johan) not yet tested that the training scripts here reproduces our original results. This repo is very similar to the internal training repo, but there might be bugs introduced by refactoring etc. Let me know if you face any issues reproducing our results (or if you somehow get better results :D).
See experiments for the scripts to train DeDoDe. We trained on a single A100-40GB with a batchsize of 8. Note that you need to do the data prep first, see data_prep.
As usual, we require that you have the MegaDepth dataset already downloaded, and that you have the prepared scene info from DKM.
