摘要

A computer system and method for performing a sort operation of the mail in which the computer system determines the location of the postal code within a digital image of an address block (20) from a mail envelope. A distance of the interval between the lines is calculated for the image and the image lines are thinned (38) for increasing the vertical separation between the lines of the address block. One median axis is determined for each line and is superimposed on the latter the digital image. It performs a broadcast operation clear beaches on the digital image from the center line at which are rated as punctuation bits of data that are not connected to the central axis, and the lines connected the lines are divided into two lines. the last line is then selected which is determined to be wide enough to contain a postal code of the limited size of the box.
