The Melanoma Classification Benchmark

We provide the first open access melanoma classification benchmark for both non-dermoscopic (MClass-ND) and dermoscopic (MClass-D) images to date. The benchmark was created with lesions of white-skinned individuals from Western populations (derived from the ISIC (dermoscopic) / Med-NODE (clinical) databases). Binary artificial intelligence algorithms trained for this target group can now be compared to 157 dermatologists for dermoscopic images and to 145 dermatologists for non-dermoscopic images of melanoma in terms of sensitivity, specificity and the receiver operating characteristic. MClass allows comparability between algorithms of different publications and provides a reference standard for binary melanoma classification of white-skinned Western populations.

The Melanoma Classification Benchmark (MClass) test-sets, individual results per dermatologist per image, file names and ground truth per image may be freely downloaded here:

100 dermoscopic images; 80 melanomas and 20 nevi (.zip): MClass-D

Results per image and per individual dermatologist (Excel-sheet): Download

File names and underlying ground truth of diagnosis (Excel-sheet): Download

100 non-dermoscopic images; 80 melanomas and 20 nevi (.zip): MClass-ND
