Example of a track of a rolled worm. Proposed method steps. (a) Subimage containing the current connected region. (b) Segmentation of the current subimage. (c) Distance transform. (d) Background transform by using the minimum width value. (e) Second iteration of the background transform. (f) Skeleton with holes. (g) Final skeleton. (h) Optimisation result.
