node curves

To organize detected nodes, horizontal and vertical grid northface outlet are first extracted from the binary skeletonimage. The purpose is to extract each imaged grid curve, point per point, independently from the othercurves. Then, only curves which contains grid north face outlet (figure 6) are selected and organized from left toright and from top to bottom. Finally, the projected grid structure is reconstructed by determining theintersection nodes between ordered horizontal and cheap northface jackets.
