A document to be processed is scanned into a machine readable image. The image is segmented into a plurality of fields. Predetermined characteristics are measured for each field and the set of characteristics is correlated with a predetermined set of characteristics derived from a reference image. The fields with the highest degree of correlation to the characteristics from the reference document are selected for further processing, e.g., optical character recognition.

[ What is claimed is:] [1.] A method of locating a specific subject image field in a subject image partitioned into a plurality of subject image fields, the method comprising the computer implemented steps of:a) determining at least one characteristic value for each of the subject image fields, wherein the characteristic value is determined by one or more characteristics selected from the group consisting of the X-coordinate of the leftmost point of the subject image field, the Y-coordinate of the uppermost pixel of the subject image field, the width of the field, the height of the subject image field, the number of pixels in the subject image field, the number of characters in the subject image field, the number of horizontal lines above the subject image field, the number of horizontal lines below the subject image field, the number of vertical lines to the left of the subject image field, the number of vertical lines to the right of the subject image field, the distance from another field having a particular string of characters, the height, width and number of pixels for each character in the subject image field, and the ASCII value of each character in the subject image field;b) determining a correlation value for each of the characteristic values by comparing each characteristic value to at least one predetermined criterion;c) combining the correlation values to yield a composite correlation value for each of the subject image fields; andd) locating the specific subject image field by determining the subject image field with the highest composite correlation value.
