Pretrained weights for **SOLD²** (Self-supervised Occlusion-aware Line Description
and Detection), used by
[`kornia.feature.SOLD2`](https://kornia.readthedocs.io/en/latest/feature.html).

SOLD² detects line segments and computes semi-dense descriptors along them using a
shared encoder. Trained on wireframe and outdoor datasets. CVPR 2021.

**Original repo:** [cvg/SOLD2](https://github.com/cvg/SOLD2)
