The sixth challenge edition is being organized as part of ISBI 2021, taking place in Nice in April 2021. In this edition, the primary focus is put on methods that exhibit better generalizability and work across most, if not all, of the 13 already existing datasets, instead of developing methods optimized for one or a few datasets only. Apart from this primary track that prioritizes highly competitive methods only, there is also a second track running that allows anyone to compete over the datasets of their choice without the hunt for generalizability across multiple datasets. The submissions for both tracks will be collected, evaluated, and announced at the corresponding ISBI 2021 challenge workshop according to the following schedule:
January 15th, 2021
|New silver reference segmentation annotations for 13 existing training datasets are released|
|December 31st, 2020||The pre-registration period for the sixth challenge edition is closed|
|January 15th, 2021||Pre-registered competitors, who passed the primary track qualification criteria, are announced|
|March 1st, 2021||Deadline for submitting results and algorithm implementations, including detailed descriptions of the approaches and parameters used|
|April 13th, 2021||ISBI 2021 Challenge Workshop|
|May-June 2021||Validation of the results submitted by re-running the respective algorithms on our evaluation servers|
