Leaflet segmentation. The scanned leaf (a) is scaled and converted to a binary image (b). The foreground pixels of the binary image are distance transformed (c). The darker the grey scale of a point, the larger its distance to the outline of the leaf. Skeleton pixels are classified according to their distance transform value (red = small, green = large). d Cut nodes (blue, c) are points on the skeleton that mark the border between leaflet pixels and petiolule pixels. Branching nodes (green, c) are points on the skeleton that mark the border between petiolule pixels and rachis pixels. e The pairs of red points (b1, b2) cut the leaf into leaflets (blue areas), petiolules (red areas) and rachis (green)
