Detailed Description

ALIKED feature detector and descriptor extractor.

ALIKED (A Lightweight Image KEYpoint Detector) is a CNN-based feature detector and descriptor extractor, as described in [Zhao23] . It produces 128-dimensional float descriptors and keypoints with sub-pixel accuracy.

The model expects RGB input [1,3,H,W] and internally converts BGR images to RGB.
