A method for automatically determining a position of an address field on a document comprising:
scanning a face of the envelope provided with the window so as to obtain scan-data representing an image of the scanned face of the envelope;
comparing the scan-data with characteristics indicative of a human-readable address;
selecting a subset of the scan-data meeting characteristics of human-readable address;
determining the position of markings represented by the selected subset of the scan-data; and
calculating the position of an address field on the document from data representing at least the position of the selected subset of the scan-data on the envelope face and a clearance or clearance range between the document and the envelope. |
