The pipeline of TopoRoot for computing fine-grained traits from a 3D image. Beginning from a 3D grayscale image \(I\) represented as a stack of image slices (A), TopoRoot first computes a topologically simple segmentation \(B\) (B), then it creates a geometric skeleton \(S\) capturing the branching structure (C), from which a hierarchy \(H\) is obtained (D) and the traits are subsequently computed. This example and the ones in Figs. 2, 3, 4 are
