Fitzpatrick17k

Overview

We annotated 16,577 clinical images sourced from two dermatology atlases — DermaAmin and Atlas Dermatologico — with Fitzpatrick skin type labels with two data annotation services: Scale AI and Centaur Labs. The Fitzpatrick labeling system, while not perfect, is a six-point scale originally developed for classifying sun reactivity of skin phenotype. The Fitzpatrick scale served as the basis for skin color in emojis and, more recently, the Fitzpatrick scale has been used in computer vision applications to evaluate algorithmic fairness and model accuracy. The annotated images represent 114 skin conditions with at least 53 images and a maximum of 653 images per skin condition.

We've included the original image sources, the training script train.py, and a notebook to compare Fitzpatrick annotations with individual typology angle scores. You can read the dataset and our analysis in our paper.

We thank Scale AI and Centaur Labs for providing Fitzpatrick Skin Type annotations for all images in this dataset for free.

Updates July 7 2022

Given the subjectivity of annotating Fitzpatrick Skin Type in images showing skin disease, we evaluated how well experts, crowds, and an algorithm compare with respect to inter-rater reliability. You can find replication files for this analysis in the annotation_evaluation folder.

Data Usage

Download the dataset

You can find the Fitzpatrick annotations in fitzpatrick17k.csv. You can download the images from their original source, which is shared in the url column of the Fitzpatrick annotations .csv. Alternatively, fill out this form and contact us and we can provide a link to all the images.

Replicate our analysis

The results from our paper can be replicated using train.py and ita_fitzpatrick_analysis.ipynb.

After you download the dataset, edit train.py by specifying the image directory of the dataset, and then run python train.py 20 full where 20 refers to the number of epochs and full refers to the full dataset.

You can check out our comparison of Fitzpatrick annotations and individual typology angle scores with the ita_fitzpatrick_analysis.ipynb
