Update notes: dataset and score metric

Dear participants,

The circumference measurements in the CSV file provided in the training dataset have been updated. You can download the corrected version via this link. In the previous version of the dataset (version 1.0), these measurements were incorrectly computed and were too large by a factor of 2, as the minor and major axes were used instead of the semi-minor and semi-major axes. No changes were introduced to the images and masks.

Additionally, this correction has been applied to the fitting ellipse function (see lines 32 and 33).

The score ranking metric has been updated to reflect that a lower NAE_AC metric is better. The term 0.5 NAE_AC has been replaced with 0.5 (1 - 0.5 NAE_AC). The updated score function is:

score = 0.5 (1 - NAE_AC) + 0.25 DSC + 0.25 WFSS

Prior submissions have been recomputed with the new formula.

Can you add the csv as a different file? As of now, the csv is inside the zip file and we have to download the large file again, which takes a long time.

Unfortunately, zenodo does not allow for that. You can divide by two the current measurements in the previous version, as a faster alternative.
