Abstract: In view of the fact that frame lines and hanging lines of a form image have the longest boundary and the boundary-labeling-automaton gives Vertex-Chain-Code of region boundaries easily, this paper proposes a new method for skew detection for a form image. The algorithm is efficient and robust against strong noise.
