3D Kidney Segmentation from Abdominal Images Using Spatial-Appearance Models

Table 1

Segmentation accuracy of our method compared with Zhang et al. [47] approach based on the DC, PVD, and BHD₉₅ metrics. Note that DC, PVD, BHD₉₅, and SD stand for Dice coefficient, percentage volume difference, bidirectional 95th-percentile Hausdorff distance, and standard deviation, respectively.

Metric	Segmentation method		value
	Our	Zhang et al. [47]
	Mean ± SD	Mean ± SD
DC (%)	97.27 ± 0.83	91.60 ± 2.29	≤10^−4
BHD95 (mm)	0.93 ± 0.49	5.36 ± 1.12	≤10^−4
PVD (%)	2.92 ± 2.21	5.00 ± 3.28	≤10^−4
