@albertcardona :) the challenge authors updated the test set since the challenge so we had to submit our masks and the winning team's masks to get the scores.
The winning Mediar team used the Cellpose flow approach (our code) and used a transformer instead of a CNN for prediction. On this dataset, it doesn't seem like the transformer improves performance. We also tested transformers on an even larger dataset and did not find a performance boost (blue and black curves) (from https://www.biorxiv.org/content/10.1101/2024.02.10.579780v2):
