Summary of Dice coefficient usage. Dice coefficient is a pairwise similarity score that we used to calculate overlap between two separate segmentations. This concept can be represented mathematically by the equations given and visually by a pairwise Venn diagram (a). In order to compare more than two segmentations at once, the Dice coefficient was modified to include all regions of overlap. An example equation and visualization is shown for a triplet comparison (b), but was extended up to sextets.
