SuperPoint is a self-supervised feature detection and description network that jointly learns interest point locations and corresponding descriptors for robust image matching.

# SuperPoint

This model uses the SuperPoint feature extractor, which detects repeatable keypoints and generates compact descriptors that are robust to viewpoint, scale, and illumination changes. It is well suited for applications such as visual localization, SLAM, structure-from-motion, image stitching, and feature-based tracking in robotics and augmented reality systems.
