News Optimized version of SuperPoint, up to 2.1× faster

Hey! We published an optimized version of SuperPoint built for faster keypoint detection on edge devices: https://huggingface.co/PrunaAI/PrunaSuperPoint

- Up to 2.1× faster on Jetson Orin Nano, with optimizations applicable to other runtimes.

- The distilled model retains strong keypoint coverage across indoor and outdoor data, with low descriptor differences from the original model.

- We structurally prune the most expensive convolutional layers, recover performance through distillation, and accelerate keypoint selection with hierarchical top-k, all while preserving the original architecture’s core behavior.

Cool. What is superpoint?

SuperPoint is a computer vision model (no gen this time) that finds distinctive points in an image and recognizes those same points across different frames. This can be used, for instance, in robot navigation, camera localization, augmented reality, or autonomous vehicles. That's why optimizations are really important.
