Abstract
Skew detection and correction poses particular challenges in deformed images, as well as images suffering from camera lens distortions or distortions caused by non-flat scanning surfaces. The current paper introduces an algorithm that yields good results on such images and proposes a confidence measurement to estimate the accuracy of the returned skew angle.
