ABSTRACT

This paper presents a method for the skew correction of text documents in digital image format, using primarily the
Hough Transform. The Hough Transform provides a good estimate of line angles in an image and this can be extended to lines of text. Positive angles between 0 and 90 degrees are estimated correctly in both test images while negative angles are estimated correctly only after implementing a solution found empirically. This routine also fits the resulting
corrected image to a given bounding box.
