From: An improved method for the segmentation of roots from X-ray computed tomography 3D images: Rootine v.2

Root diameter distribution and root outline accuracy for the worse and best case scenario. a, c RLD distribution as a function of root diameter for Rootine v.1 and v.2 and the destructive sampling data obtained by scanning washed-off roots (WinRHIZO) for the worse case and the best case scenario, respectively. The semitransparent ribbon denotes the standard error of the measurements (n = 12). b, d Visual comparison of the segmented root diameter outlines for both Rootine v.1 and Rootine v.2 supported by the original X-ray CT grayscale data for the worse case and the best case scenario, respectively. Roots detected by both algorithms are depicted in black, the ones only detected by Rootine v.2 are shown in blue, whereas roots only detected by Rootine v.1 are shown in red. Dashed horizontal black lines highlight the fact that Rootine v.2 better captures root diameter in comparison with Rootine v.1
