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.

Leaderboard Synaptic Cleft Detection

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).

FP, FN
The False Positives and False Negatives synaptic partner pairs. See metrics for details.

For each value, lower is better.
