Illustration for calculation of volumetric Dice score coefficient (DSC), Hausdorff distance, and surface DSC. The solid line represents the ground truth contour, whereas the dashed line is the prediction. i. A Volumetric DSC, defined as the union of two volumes (green volume region) normalised by the mean of the two volumes. ii. Hausdorff distance, defined as the maximum nearest neighbor Euclidean distance (the arrow). iii. Surface DSC, is defined as the union of two contours (yellow contour region) normalised by the mean surface of the two contours.—modified after129.
