Dice coefficient and hausdorff distance

WebAgreement between segmentations on T2w-images between urologists and radiologists was assessed with Dice similarity coefficient (DSC) and 95 % Hausdorff distance (95 % HD). Differences in similarity scores were compared using Wilcoxon test. Differences depending on lesion features (size, zonal location, PI-RADS scores, lesion distinctness) were ... WebMay 19, 2024 · The Dice coefficient is calculated to compute the degree of volumetric overlap of the assignments by manual segmentation. The range for Dice coefficient value is 0 to 1 [ 24, 25, 26 ]. Hausdorff distance is the greatest of all distances from a point in one set to the closest point in the other set [ 23, 27 ].
