Dataset Card for Curated Gold Standard Cuthill Dataset

Dataset Description

Dorsal full body images of subspecies of Heliconius Erato and Heliconius Melpomene (18 subspecies total). 960 images with 320 specimens Each image is a low-resolution ("images were then cropped and resized to a height of 64 pixels (maintaining the original image aspect ratio and padded to 140 pixels wide) Hoyal-Cuthill 2019 ) photographed in RGB Low resolution images were then transformed using AccuityView (doi: https://cran.r-project.org/web/packages/AcuityView/index.html, and estimates of accuity from: http://www.empiricalimaging.com/knowledge-base/acuityview/, https://www.annualreviews.org/doi/10.1146/annurev.ento.42.1.147 Users should know that since Land 1997, more recent estimates of insect visual accuity have been created. There are (3 images of each specimen Original/ Bird transformed/ Butterfly transformed). This data represents a subset subset of images processed from Cuthill, et. al. dataset available at doi:10.5061/dryad.2hp1978.

Only Dorsal Images

Note: dorsal_images_cuthill contains processed dorsal images from the original Cuthill dataset (all 1,234 specimens).

Data Instances

  • Type: PNG
  • Size: 128px x 128px
  • Background: [210, 210, 210] (gray)
  • Fit in frame: Most padding is above and below the image, some on the left and right.
  • Ruler or Scale: None
  • Color (ColorChecker, white-balance, None): None

Data Fields

In Hoyal_Cuthill_GoldStandard_metadata_cleaned.csv:

  • NHM_Specimen: Natural History Museum Specimen number
  • Image_filename: filename of image of specimen
  • View: whether ventral or dorsal view of specimen (all dorsal)
  • Species: species of specimen (melpomene or erato)
  • Subspecies: subspecies of the specimen
  • Sex: sex of the specimen (male or female)
  • addit_taxa_info: additional taxonomic information (subspecies)
  • type_stat: [More Information Needed] 'ST', 'PT', or 'HT', but mostly null
  • hybrid_stat: hybrid status ('valid subspecies', 'subspecies synonym' or 'unknown' (only 1))
  • in_reduced: [More Information Needed] 0 or 1 to indicate yes or no
  • locality: where specimen was collected
  • lat: latitude where specimen was collected
  • lon: longitude where specimen was collected
  • speciesdesig: species designation, first initial of species '.' subspecies (eg., 'm. rosina')

Train_Test_Curated_GoldStandard_Hoyal_Cuthill.csv has three additional columns:

  • Image_filename_png: filename of (png) image of specimen, dorsal_images_cuthill/ + <Image_filename_png> is the filepath for the processed dorsal image
  • subset: whether this is part of the training or test set (train or test)
  • filepath: the filepath for the train or test image

Acuity_Curated_GoldStandard_Hoyal_Cuthill.csv also has Image_filename_png and subset, but subset references the bird and butterfly acuity training and test sets. Additionally, it has columns:

  • bird_filepath: the filepath for the bird acuity version of the image
  • butterfly_filepath: the filepath for the butterfly acuity version of the image

Data Splits

There are 250 images in each training set and 70 in each test set.

RGB training images are in train folder and testing are in test.

For bird and butterfly acuities, their respective training and test images are in the train_bird (train_butterfly) and test_bird (test_butterfly) folders.

All of these folders are further subdivided by the subspecies. Filepaths to access these images are provided in Train_Test_Curated_GoldStandard_Hoyal_Cuthill.csv and Acuity_Curated_GoldStandard_Hoyal_Cuthill.csv, respectively.

Dataset Creation

Processing steps included:

  1. Hybrid Separation
  2. Label Correction
  3. Removal of subspecies with no mimic pairs
  4. Make background uniform across all images
  5. Make image square via padding

Curation Rationale

This dataset was curated for training a model to classify different species of Heliconius Butterflies and to take into account mimicry between species and acuity of the observer (bird, butterfly, or human/other). The original data (Cuthill et al 2019) had misclassified species/subspecies and some locality/ collection sites were outside the known range of the butterflies. It also contained hybrid and aberrant samples, that had the potential to muddle classification results. To prevent this, the data was further refined by several Heliconius experts to remove hybrid and aberrant samples. Lastly, bird and butterfly acuities were added to provide another level of analysis using AccuityView and estimates of observer accuity.

Annotations

Annotation process

The original data has some misclassified species/subspecies, and had multiple hybrid samples. These samples were removed by hand by OM, CL, JM, KK. Some localities were outside the known range of the butterflies, and were removed using QGIS and known sub species ranges.

Considerations for Using the Data

Social Impact of Dataset

N/A

Discussion of Biases

Biased towards species and subspecies within Heliconius. Focused on Heliconius erato and Heliconius melpomene

Other Known Limitations

  • No genetic data available.

  • Non-uniform distribution of subspecies (imbalanced).
