通过检测框图确定表格倾角的直线检测新方法

A New Line Detection Method Used To Measure A Form′s Skew Angle Quickly

本算法利用数字影像中直线段的结构特征高效地检测出表格的一条边框线,并由此获得所需的角度值。这一算法也可以用于快速检测其它影像中较长的直线段。

A new method is given here to measure this sort of skew angle rapidly, it first detects one of the form＇s frame lines by using the structural characteristics of digital lines, and then calculates the skew angle＇s value. The method may also be used to detect long line segments efficiently in other kinds of images.
