EfficientLoFTR ONNX Weights

This repository contains the ONNX-optimized weights for EfficientLoFTR, a model used for finding matching points between pairs of images.

By converting the original PyTorch model weights into the ONNX format, these files allow you to run fast feature-matching inference on both CPU and GPU without needing to install the heavy PyTorch framework.

Available Files

• eloftr_outdoor_full.onnx: The standard version of the model, optimized for the best matching quality.
• eloftr_outdoor_opt.onnx: An efficiency-focused version of the model, optimized for faster inference speed.

How to Use

The easiest way to load and use these files is through the spatialhub Python library.
