CREMI score: The geometric mean of (VOI split + VOI merge) and ARAND.
VOI split and merge: The Variation of Information between a segmentation X and ground truth Y. The split and merge parts correspond to the conditional entropies H(X|Y) and H(Y|X), respectively.
ARAND: The Adapted Rand Error, i.e., 1.0 - Rand F-Score.

For each value, lower is better.

Results for the synaptic cleft detection category, averaged over all samples.

CREMI score: The mean of ADGT and ADF. We are not including the F-Score for now, as our current way of computing it can lead to unfair comparison. We are working on a more robust measure and will update the results accordingly.
FP, FN, and F-Score: The False Positives, False Negatives, and the resulting F-Score in the clefts detection volume. See metrics for details.
ADGT: The average distance of any found cleft voxel to the closest ground truth cleft voxel.
ADF: The average distance of any ground truth cleft voxel to the closest found cleft voxel.

For each value, lower is better (F-Score shown as 1 - F-Score).

Results for the synaptic partner identification category, averaged over all samples.

CREMI score: 1 - F-Score of the FP and FN.
FP, FN: The False Positives and False Negatives synaptic partner pairs. See metrics for details.

For each value, lower is better.
