The following rules are applicable to those who request to participate (individually or as a team) and download the data:


       Participant Details:

  • All the information while registration as a team or individual must be complete and correct. Note: Anonymous registrations are not allowed.

       Disclosure of the Competition Results:

  • Evaluation of results uploaded (for any of the sub-challenge) to this website will be made publicly available on the leaderboard of this site, and by submitting results, you grant us permission to publish our evaluation.

       Submission of Paper:

  • To participate in the challenge and have your results visible on this website it is mandatory to submit a 4-page paper in appropriate ISBI style to the organizers in which you explain your algorithm.

  • Participants can submit up to three methods to be evaluated per team for each sub-challenge.

  • Multiple submissions are only allowed when the utilized algorithm differs significantly from the algorithm used in the first submission. The consecutive submissions must include a short description of the difference of the method from the previous submissions.

       Ownership of Algorithms:

  • Participating teams maintain full ownership to their algorithms and associated intellectual property they develop in course of participating in the challenge.

  • The top-performing participating teams and individuals (decided by the experts based on the performance of the method) will be invited to contribute to a joint journal paper(s) with maximum 2 authors per team describing and summarizing the methods used and results found in this challenge. The paper will be submitted to a high-impact journal in the field.

  • The organizers will review the paper for sufficient detail to be able to understand and reproduce the method and hold the right to exclude participants from the joint journal paper in case their method description was not adequate.

  • An appropriate citation is to be made in scientific publications (journals, conference papers, technical reports, presentations at conferences and meetings) that use the data shared in this challenge. The citation must refer to the data, data descriptor and the publication that is an outcome of this challenge.
