Table 1.

Testing phase fivefold cross-validation: the quantitative MRI prostate segmentation performance results of comparing AAM + AlexNet (Alex), HNN MRI alone (HNN_mri), HNN MRI + CED (HNN_ced) methods in four metrics of DSC (%), Jaccard index (IoU) (%), HDRFDST (mm), and AVGDIST (mm). Best performance methods are shown in bold.
