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) WebMost short line segments are retained in the image at the bottom of the hierarchy, but some non-road segments are also retained. Hence, line images in the hierarchy complement each other, and thus they can be combined to yield a more reliable road network from images. 3.2 Hierarchical Grouping of Line Images
