摘要: 根据表格图像中表格的框线或悬线具有最长的边界,以及边界标定自动机能获得区域边界的优点,提出了一种新的表格图像文件倾斜矫正的方法.该方法使用简便,而且在大噪声的背景下也能使用.

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.
