The BCN20000 dataset consists of dermoscopic images of skin lesions taken between 2010 and 2016 at the Hospital Clínic in Barcelona. It aims to tackle the challenge of classifying dermoscopic images of skin cancer under diverse conditions, including lesions in challenging locations (such as nails and mucosa), large lesions exceeding the dermoscopy device's aperture, and hypo-pigmented lesions.
