Computing a cycle-free skeleton. A An initial curve skeleton \({S}_{0}\) computed by the methods of [21, 22], where color indicates the thickness of the roots (redder curves lie in thicker roots). B A skeleton junction (in the boxed region in (A)) caused by two roots touching in the segmentation, which leads to a cycle in the skeleton. C The same region on the final skeleton \(S\) where the cycles have been removed using a graph-based algorithm
