A deskew algorithm of documentary images based on WVD
Ran Xiang-jin · Applied science and technology · 2006
This paper describes an efficient and automatic deskew algorithm for documentary images.WVD(Wigner-Ville distribution) is attained by using the horizontal projection value of the documentary image.The skew angle can be obtained by calculating the maximal extreme value of WVD.The experimental results confirm the effectiveness of the algorithm.
