This repository contains a re-implementation of our paper Interpretable Semantic Photo Geolocation.

Semantic Partitioning (SemP)

Subpackage semantic_partitioning contains:

See semantic_partitioning/README.md for details.

Classification

Subpackage geo_classification contains:

See geo_classification/README.md for details.

Extended MP-16 Dataset (EMP-16)

To overcome the need for a full installation of a reverse geocoder such as Nominatim, we provide the postprocessed output of the reverse geocoding for the MP-16 dataset1 along with the validation set (YFCC-Val26k) which originally comprising photos and respective GPS coordinates. Both datasets are subsets of the YFCC100M dataset2 which are crawled from Flickr.

Further details: semantic_partitioning/README.md

Concept Influence

We provide the underlying functionality to compute the presented concept influence metric based on given semantic maps and attribution/explanation maps. Please note, that the computation of both semantic maps and explanation maps are not part of this repository.


Requirements

conda env create -f environment.yml
conda activate github_semantic_geo_partitioning
# cd in respective subpackages
cd semantic_partitioning
cd geo_classification
