Image Geolocation Thesis Demo

This Demo showcases the developed models and allows interacting with the optimized prototype.

Try the "Image Geolocation Demo" tab with your own images or with one of the examples. For all example image the ground truth is available and will be displayed together with the model predictions.

In the "Versus Mode" tab you can play against the AI, guessing the country and continent where images where taken. Images in the versus mode are from the Im2GPS and Im2GPS3k geolocation literature benchmarks. Can you beat the AI?

Note that inference in this publicly hosted version is very slow due to the limited and shared hardware. This demo runs on the Hugging Face free tier without GPU acceleration. Running the demo with a GPU allows for inference times between 0.5-2 seconds per image.
