We are happy to announce the kickoff of the 2019 ISIC Challenge on Skin Lesion Analysis. 25,332 images are available for training across 8 different categories. Additionally, the test dataset (planned release August 2nd) will contain an outlier class (not represented in the training data), which developed artificial intelligence and machine learning systems must be able to identify.

Two tasks are defined: 1) classify dermoscopic images without meta-data, and 2) classify images with additional available meta-data. Task 1's deadline will be August 9th. Task 2's deadline will be August 16th, after release of test meta-data on August 9th. Participants of Task 2 must submit to Task 1 as well, though participants can submit to Task 1 alone.

Please visit the challenge website for more information, to download data, and to ask questions on the challenge forum: http://challenge2019.isic-archive.com/
