Pretrained weights for ALIKED (A Lighter Keypoint and Descriptor Extraction Network via Deformable Transformation), used by kornia.feature.ALIKED.

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.
