# Separate_segmented_train_test_splits_80_20
This subset of the 2018 NEON Ethanol-preserved Ground Beetles dataset was generated as part of a project at [BeetlePalooza 2024](https://doi.org/10.5281/zenodo.15540300). The code to generate this collection of images is available in the [Beetle_Palooza_image_separation notebook](https://github.com/Imageomics/2018-NEON-beetles-processing/blob/main/notebooks/Beetle_Palooza_image_separation.ipynb) provided in the [dataset processing repository](ttps://github.com/Imageomics/2018-NEON-beetles-processing). There were two directories of images generated during this processing [`group_images_masks/`](https://huggingface.co/datasets/imageomics/2018-NEON-beetles/tree/7b3731daca1f91931f8086d6782ab9150ab8ce26/group_images_masks) and [`separate_segmented_beetle_images/`](https://huggingface.co/datasets/imageomics/2018-NEON-beetles/tree/7b3731daca1f91931f8086d6782ab9150ab8ce26/separate_segmented_beetle_images), which have associated metadata files in the [metadata directory of the processing repo](https://github.com/Imageomics/2018-NEON-beetles-processing/tree/main/metadata); they are `group_images_masks_sb.csv` and `group_images_sb.csv`, respectively.

## About this Data Subset
This folder contains cropped images of approximately 7,000 individual images for beetles from the following species (not really 12 species: repeated species epithet in _Pterostichus melanarius melanarius_ indicates this is the nominotypical subspecies of _Pterostichus melanarius_).
1. _Calathus advena_
2. _Cyclotrachelus torvus_
3. _Chlaenius aestivus_
4. _Euryderus grossus_
5. _Harpalus pensylvanicus_ OR _Pterostichus pensylvanicus_ --- this species epithet seems to have two different genera associated to it and will thus require more effort for alignment. Hopefully, it's just a matter of merging on an ID from the original dataset but look at the filename generation to figure it out.
6. _Pterostichus melanarius_
7. _Pterostichus restrictus_
8. _Pterostichus melanarius melanarius_ — nominotypical subspecies of _Pterostichus melanarius_
9. _Pterostichus lachrymosus_
10. _Carabus goryi_
11. _Cratacanthus dubius_
12. _Synuchus impunctatus_
