A method for identifying document edges collects a predetermined number scanlines of the document against a light backing and a dark backing. A first set of first-order statistics are calculated from the image data obtained by scanning the document against the light backing. A second set of first-order statistics are calculated from the image data obtained by scanning the document against the dark backing. A document edge is detected using the first and second sets of first-order statistics.
