Webarxiv.org Web1 de ago. de 2008 · The hierarchical algorithm, as shown in Fig. 1, consists of four stages: (i) Line segment extraction—at the lowest level, the image is described as a set of edge pixels, from which line segments are extracted. (ii) Line segment linking—line segments that are potential candidates of elliptic arcs are linked to form arc segments. (iii)
