TABLE I.

Mean values and standard deviations (Std) of DSC, sensitivity, PPV, and ASD between automatic segmentations and manual segmentations for our proposed method and three other methods on the internal dataset. NA in the table means the corresponding measurement was not reported in the literature. The best performance of each measurement is shown in bold lettering.
