Segmentation of roots in soil with U-Net

Table 4 Mean and standard deviation of results on images containing roots

	Frangi	U-Net
\(F_1\) mean	0.463	0.705
\(F_1\) standard deviation	0.085	0.040
Recall mean	0.361	0.749
Recall standard deviation	0.081	0.042
Precision mean	0.660	0.666
Precision standard deviation	0.087	0.043

These are computed by taking the mean of the metrics computed on each of the 8 images containing roots. The 2 images without roots are excluded as for these \(F_1\), precision and recall are undefined
