Abstract
A method and system. An initial angle of rotation is determined by sampling test angles of rotation of a captured digital image and analyzing resultant rotated images to determine a resultant rotated image with a highest number of substantially empty lines. The captured digital image is rotated by the initial angle of rotation to generate a first rotated image. A representative line of each line area of multiple text line areas of the first rotated image is generated. A slope of each representative line is calculated. An aggregated slope of the representative lines is determined. The aggregated slope is converted to a refining angle of rotation. The refining angle of rotation is validated by finding points of intersection of lines connecting opposing ends of adjacent representative lines. The first rotated image is rotated by the refining angle of rotation to result in a final rotated image.
