DETECTING SKEW IN DIGITISED IMAGES |
摘要 |
<p>A method of detecting skew in a digitised document image as described. The method comprises forming a transformation of the image, to generate an array H(D, A) representing the number of black pixels which lie on lines with angle A and perpendicular displacement D. The dominant angle A in this array, determined by calculating an energy function from the array, is taken as the angle of skew.</p> |
