SuperPoint

This repository contains the [SuperPoint](https://arxiv.org/abs/1712.07629) model converted to run on the Axera NPU. SuperPoint is a self-supervised framework for training interest point detectors and descriptors, suitable for a large number of multiple-view geometry problems in computer vision.

This version has been quantized using w8a16 and is optimized for use with Pulsar2 (version 4.2).
