CHIMERA Challenge Rules

  • All participants must form teams, even if the team consists of a single participant. Each individual may only be a member of one team.

  • Participants found using multiple or duplicate Grand Challenge profiles will be disqualified.

  • Anonymous participation is not allowed. To appear on the validation/testing leaderboards, participants must display their real name and affiliation (university, institute, or company, and country) on a verified Grand Challenge profile.

  • Members of sponsoring or organizing centers may participate but are not eligible for prizes or final rankings in the Closed Testing Phase.

  • This is a code execution challenge. Participants must submit a Docker container with everything needed for inference. Predictions are not submitted directly.

  • All Docker containers will be executed in an offline environment with no internet access. All necessary resources (e.g., pre-trained weights) must be included in the container prior to submission.

  • Use of external datasets and pre-trained models is allowed if they are freely and publicly available under a permissive open-source license. The use of such resources must be clearly declared in the algorithm name, on the algorithm page, and/or in a supporting publication or URL.

  • Participation in the Closed Testing Phase requires submission of:

    1. 6-page manuscript (excluding references), formatted using the MICCAI Springer template
    2. A public or private GitHub URL with the algorithm’s source code, released under a permissive license

  • Participants are responsible for ensuring that their algorithms adhere to the specified compute limits.

  • Results obtained using the CHIMERA public training dataset may not be published until after the embargo period (i.e., after the CHIMERA challenge journal paper and the baseline paper are published). When publishing, participants must cite the challenge publication.

  • The organizers reserve the right to disqualify participants or teams at any point for unfair or dishonest practices.

  • Participants may withdraw from the challenge at any time. However, previous submissions and any results already published cannot be retracted.

  • The competition is open to participants worldwide, except for residents of North Korea, Crimea or any other place covered by Financial measures, Restrictions on goods EU sanctions. The aforementioned regulation is in place because of a requirement to conform to EU regulations concerning the provision of resources and transfer of finances (challenge award money, etc...)

  • Participants can participate in only one task, and participation in all tasks of the CHIMERA challenge is not mandatory.
