Examples of histograms between two different subsets of tumors in CT Liver Tumor Segmentation and MRI brain tumor segmentation datasets. (A) CT: HCC and HEM at site C (arterial phase): EMD = 3.3443, BD = 0.0699, CSD = 0.1278, KSD = 0.28. (B) CT: FNH and cyst at site C (arterial phase): EMD = 23.7903, BD = 1.4561, CSD = 0.9029, KSD = 0.48. (C) CT: tumor size 1 (≤15 cm3) and size 2 (15EN_DASH50 cm3) (PV phase): EMD = 0.9238, BD = 0.0071, CSD = 0.0139, KSD = 0.11. (D) CT: tumor size 3 (50–130 cm3) and size 4 (>130 cm3) (PV phase): EMD = 0.7824, BD = 0.0114, CSD = 0.0217, KSD = 0.09. (E) MRI: enhancing brain tumors at site 1 and site 4: EMD = 0.5425, BD = 0.0022, CSD = 0.0042, KSD = 0.14. (F) MRI: enhancing brain tumors of SI-Q1 and SI-Q4 subsets: EMD = 12.8243, BD = 0.3104, CSD = 0.3939, KSD = 0.30. BD = Bhattacharyya distance, CSD = χ2 distance, EMD = earth mover’s distance, FNH = focal nodular hyperplasia, HCC = hepatocellular carcinoma, HEM = hemangioma, KSD = d statistic of Kolmogorov-Smirnov test, Q = quarter, SI = signal intensity.
