Abstract

An oversize document, one that is larger than the platen of the scanner, can be scanned in several segments then stitched together electronically. A method is described to analyze the scan segments to determine the orientation, magnification and translation of the different scanned segments to be stitched together. Operator assistance is required to identify salient features in the different segments to be analyzed. The location of these features is determined by calculating the centroid from a rough crop of each feature. The orientation, magnification, and translation of the scanned segment can all be determined from a comparison of the locations of the identified features. The segments are blended together with standard blending techniques.
