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 photographed in RGB with bird and butterfly acuity included (3 images of each specimen). Subset of images processed from Cuthill, et. al. dataset available at doi:10.5061/dryad.2hp1978.

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:

Hybrid Separation
Label Correction
Removal of subspecies with no mimic pairs
Make background uniform across all images
Make image square via padding

Curation Rationale

[More Information Needed]

The original data has some misclassified species/subspecies and some localities were outside the known range of the butterflies. Furthermore, the bird and butterfly acuities were not part of the original dataset and provide another level of analysis.
