# kornia/lightglue

Pretrained weights for **LightGlue** (Local Feature Matching at Light Speed),
used by [`kornia.feature.LightGlue`](https://kornia.readthedocs.io/en/latest/feature.html).

LightGlue is a sparse feature matcher built as a pruned transformer that early-exits
unpromising keypoint pairs at each layer, achieving near-SuperGlue accuracy at a
fraction of the latency. ICCV 2023.

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