# SuperPoint: Optimized for Qualcomm Devices

SuperPoint is a self-supervised framework for detecting interest points and computing their descriptors in a single forward pass. It uses a VGG-style encoder shared between a keypoint detector head and a descriptor head, trained via homographic adaptation on synthetic shapes and real images. The model outputs up to 500 keypoints per image with 256-dimensional L2-normalised descriptors, suitable for feature matching, visual localisation, and SLAM.

This is based on the implementation of SuperPoint found [here](https://github.com/rpautrat/SuperPoint).
This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/superpoint) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).

Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device.

### Option 2: Export with Custom Configurations

Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/superpoint) Python library to compile and export the model with your own:
- Custom weights (e.g., fine-tuned checkpoints)
- Custom input shapes
- Target device and runtime configurations

This option is ideal if you need to customize the model beyond the default configuration provided here.

See our repository for [SuperPoint on GitHub](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/superpoint) for usage instructions.
