Estimation of root central line 2D + t coordinates. Left: labelled segmentation, comprising successive growth intervals of a single root, from purple (earliest interval) to yellow (latest interval). Middle: corresponding elements (edges and vertices) in the min-weighted spanning forest \(F\) extracted from the region adjacency graph. Right: Corresponding elements in \(I\), the dual graph of \(F\), whose spatial coordinates of vertices are estimated from the geometry of the separation between successive growth intervals (blue arrow and blue line)
