• Popis: Assistive tools to aid in skin cancer detection are experiencing an unprecedented rise with the accessibility of robust and accurate deep learning models. However, in the present applications, only a negligible number of dermatology images come from patients with Fitzpatrick skin types IV–VI, representing brown, dark brown or black skin, respectively. In this study, we demonstrate the utilization of Zero-Shot Text-to-Image autoregressive models to generate synthetic medical data for improved balance in training CAD classification models with minimized racial bias. Synthetically generated images of skin lesions were assessed by an experienced dermatologist using the ABCD rule and differential diagnostics, and subsequently validated using a pre-trained ResNet50V2 multi-class classification model.
