Abstract
In a document analysis system the skew error detection is one of the most crucial parts. This paper describes a method that takes advantage of texture orientation analysis in order to find the skew error from the source document. The source image is first shrunk to melt the characters in together, reduce noise and decrease the amount of computing. After pre-processing a texture direction analysis method is applied. This procedure produces an unambiguous angle in degrees as the skew angle.
