Claim One:
1. A method for use in image reconstruction for calculating the width and height of a graphical image having unknown dimensions, said graphical image being represented by graphical image data, said graphical image data comprised of a plurality of data elements, each of said data elements representing a characteristic of a region of said graphical image, said method employing a computing system having one or more processors and a memory device, said method comprising the steps of: storing said graphical image data in said memory device; analyzing said memory device to obtain a size in memory units of said stored graphical image data using at least one of said processors, said size representing the area of said image in pixel units; obtaining a plurality of pixel width-height pair estimates, each of said pixel width-height pair estimates having a product equal to said area of said image in pixel units; calculating an error index for each of said width-height pair estimates, said error indexes evaluating the correlation of brightness values of vertically adjacent pixels in said stored graphical image data corresponding to a configuration of said graphical image having the width and height associated with the corresponding width-height pair estimate; and determining the width and height in pixels of the graphical image by selecting the width-height pair estimate having the lowest error index to produce graphical image data corresponding to a graphical image of known dimensions.
