Polar perspectives: a deep dive into geo-referencing historical Antarctic photos

Felix Dahle, Bert Wouters, Roderik Lindenbergh(2024)

International Journal of Digital Earth

We developed a workflow to geo-reference historical aerial imagery with a use-case on the Antarctic Peninsula. Using modern algorithms for tie-point matching (LightGlue), we find similar points on historic and modern Sentinel-2 imagery for geo-referencing. A special focus is the tie-point matching, adapted to work with historical and large-format imagery.

ISPRS Open Journal of Photogrammetry and Remote Sensing

Building on previous work, we extend the semantic segmentation of historical photographs of Antarctica using U-nets. We compare multiple hyper-parameters and augmentation methods to identify the optimal settings for segmentation of Adelaide Island.

XXIVth ISPRS Congress 2022 (Nice, France)

Semantic segmentation is applied to historical photographs of Antarctica using a U-net based machine learning approach. Results show the method handles very challenging images even when trained with only a small number of training samples, capturing the general semantic meaning of a scene.
