 # HF-Net: Robust Hierarchical Localization at Large Scale
 
 This repository accompanies our CVPR 2019 paper *[From Coarse to Fine: Robust Hierarchical Localization at Large Scale](https://arxiv.org/abs/1812.03506)*. We introduce a 6-DoF visual localization method that is accurate, scalable, and efficient, using HF-Net, a monolithic deep neural network for descriptor extraction. The proposed solution achieves state-of-the-art accuracy on several large-scale public benchmarks while running in real-time.
