Quantitative comparison of the independent testing set among different methods

Methods	Independent testing set (Dice)		Independent testing set (Jaccard)
	Ulna	Radius	Ulna	Radius
U-Net	0.9767 ± 0.0258	0.9836 ± 0.0114	0.9557 ± 0.0444	0.9681 ± 0.0213
FCN	0.9755 ± 0.0113	0.9824 ± 0.0070	0.9525 ± 0.0212	0.9655 ± 0.0134
Ours	0.9806 ± 0.0164	0.9860 ± 0.0076	0.9624 ± 0.0295	0.9725 ± 0.0142

The results are expressed as the mean ± standard deviation. Bold values indicate the best score obtained for ulna and radius segmentation
