Similar to how clinical trials have to be registered before starting, the complete design of accepted MICCAI challenges will be put online before the challenges take place. Changes to the design (e.g. to the metrics or ranking schemes applied) must be well-justified and officially be registered online (as a new version of the challenge design). Registering challenges is a big step towards higher quality challenges. It not only has the potential to lead to more thoughtful challenge designs but also provides all the information necessary for challenge participants. Furthermore, all changes will be transparent to the community, ensuring increased quality control. Below, the registered challenges are listed.

MICCAI 2023

Organizing a challenge based on an accepted challenge proposal may be time-consuming, especially when large-scale data annotation is necessary. To address the traditionally tight schedule between MICCAI challenge acceptance and organization, we offered an early review of MICCAI 2023 challenge proposals in the call for MICCAI 2022 challenges. Organizers interested to organize a challenge in 2023 were able to receive an early acceptance that leaves time for careful preparation of the challenge. Only convincing challenge proposals were accepted in this round. Other challenges were asked to resubmit in the next call for challenges.

MICCAI endorsed events

The number of submitted challenge proposals is steadily increasing. Due to limited room capacities, not every interesting challenge can be accepted for an ongoing MICCAI event. Therefore, we decided to accept challenges as MICCAI endorsed online-only events, which are not bounded to a specific conference, but organized under the MICCAI umbrella.
