The DArmstadt Skin Tone (DAST) database contains portrait images from a large variety of capture subjects (light skin to dark skin). Face images are captured under controlled conditions and include ICAO compliant samples as well as systematically overexposed and underexposed images for each subject. In addition, for each subject multiple ground truth measurements for the skin tone are included. The dataset is intended to support the evaluation of demographic bias in face image quality measures and to facilitate the development and benchmarking of skin tone classification.
