A collection of 248 melanocytic lesions that were submitted by experts as exemplars for 1 out of 31 dermoscopic features (8 images per feature), and used for evaluating agreement among (unrelated) experts on (1) malignancy, (2) feature presence, and (3) feature localization within a lesion. The repository of image masks and superpixel annotations is here:
