Dice coefficient and hausdorff distance
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 ]. WebMar 1, 2024 · Dice coefficient and Hausdorff distance In the 10 segmented images of this study, the largest Dice coefficient is 0.94, the worst is 0.64, and the average is 0.76, as shown in Fig. 3. The Hausdorff distance results of the 10 test image segmentation results are shown in Fig. 4.
