+
+Pretrained weights for **ALIKED** (A Lighter Keypoint and Descriptor Extraction Network
+via Deformable Transformation), used by
+[`kornia.feature.ALIKED`](https://kornia.readthedocs.io/en/latest/feature.html).
+
+ALIKED uses deformable convolutional heads to detect keypoints that are inherently
+invariant to affine deformations, with a sparse descriptor extraction step.
+IEEE Transactions on Instrumentation and Measurement, 2023.
