PED-UFES-20

Dataset Information

The PAD-UFES-20 dataset contains 2298 skin lesion images taken with various smartphones from 1373 patients. This dataset involves 6 categories, three of which are types of skin cancer: Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC), and Melanoma (MEL); the other three are skin conditions: Actinic Keratosis (ACK), Seborrheic Keratosis (SEK), and Nevus (NEV). The SCC category also includes Bowen's disease (BOD). All BCC, SCC, and MEL cases in the dataset have been biopsy-verified, while the other categories have been diagnosed by a group of dermatologists. For each image in the dataset, the authors provide the image category label, patient age, skin lesion location, and skin lesion diameter.

The collection and preparation of the PAD-UFES-20 dataset received support from the Skin Disease & Surgery Assistance program project of the Federal University of Espírito Santo. This non-profit project aims to assist researchers in developing automatic identification algorithms and software to provide free skin disease diagnoses for low-income individuals who cannot afford private treatment.
