This challenge is evaluated using the Dice Similarity Coefficient (DSC) score. The DSC score is calculated as follows:

for both the positive and negative pixels.

Participants are required to upload a CSV file containing the segmentation for the test data encoded in the run-length encoding format (details in the Submission section). The final score for a participant will be based off the DSC score for all testing data released, and the DSC score will be the average across all LA cavity segmentations.
