Abstract
A method and system for automatic correction of skewing of digital images. A captured digital image s provided. An initial angle of rotation is determined by sampling test angles of rotation of the input image and analyzing resultant rotated images to determine a resultant rotated image with a highest number of substantially empty lines. The input image is rotated by the initial angle of rotation to generate a first rotated image which is processed to determine a refining angle of rotation as follows: determining text line areas of the first rotated image; generating a representative line of each text line area; calculating a slope of each representative line; and determining an aggregated slope of all the representative lines. The aggregated slope is converted to the refining angle of rotation. The first rotated image is rotated by the refining angle of rotation to result in a final rotated image.
