Visualisation of Similarity Metrics. (a) The Dice Similarity Coefficient Represents an Index of Overlap (A ∩ B) Between Two Segmentations, Calculated as $\text{DSC}=\frac{2\times A\cap B}{A+B}$ where 0 Represents No Overlap and 1 Perfect Alignment. (b) Two Segmentations A and B will have A Small Hausdorff Distance (d₁) if the Segmentations are Close to Each Other. (c) Two Segmentations A and B will have a Large Hausdorff Distance (d₂) if the Segmentations are Far from Each Other.
