michalmolas/birds-of-poland

This dataset contains images of birds that can be found in Poland (according to https://avibase.bsc-eoc.org/checklist.jsp?region=PL).

Fetching

The images were fetched from iNaturalist API (the photos have variouc cc licences, individal credits can be found in the metadata.jsonl file). Only observations from Europe were considered (there was too little observations in Poland).

For each species 600 photos were fetched (or in some cases, all available), some of them might have been filtered out in the processing phase, so number of images per class varies.

Processing

The photos were run through a Faster R-CNN network, to detect bird bboxes and scaled to 224x224.

Image was only accepted if there was exactly one match found, to avoid using photos with multiple (or none) species in one picture.
