Abstract
A method and an apparatus which scans and recognizes a page having columns of text or pictorial images. The scanned page is partitioned into blocks of scanlines and the column gap between the columns are identified by a projection profile process. With this technique the page can be severely tilted while under scan and still be properly recognized.
