# kornia/dedode

Pretrained weights for **DeDoDe** (Detect, Don't Describe — Describe, Don't Detect),
used by [`kornia.feature.DeDoDe`](https://kornia.readthedocs.io/en/latest/feature.html).

DeDoDe trains detection and description independently: the detector is trained to
find repeatable 3D points, the descriptor is trained separately for matchability.
Supports upright and rotation-equivariant (C4 / SO2) variants. 3DV 2024.

**Original repo:** [Parskatt/DeDoDe](https://github.com/Parskatt/DeDoDe)
**Rotation-equivariant variants:** [georg-bn/rotation-steerers](https://github.com/georg-bn/rotation-steerers)
