Method and apparatus for alphanumeric recognition
First Claim
1. A method of alphanumeric character recognition, comprising:
- receiving a set of unknown characters from an imaging system;
receiving a set of known characters from a memory device;
creating a first set of pairs of characters from the set of unknown characters;
creating a second set of pairs of characters from the set of known characters;
generating a matrix having a plurality of cells, wherein each cell of the plurality of cells contains a pair of characters;
interrogating the plurality of cells of the matrix with the first set of pairs of characters and generating a first result;
interrogating the plurality of cells of the matrix with the second set of pairs of characters and generating a second result;
comparing the first result with the second result;
taking a first predetermined action if the first result matches the second result; and
taking a second predetermined action if the first result does not match the second result.

Abstract
A method and apparatus for recognizing alphanumeric characters in which a set of unknown characters is received from an imaging system and a set of known characters from a storage device. A first set of pairs of characters is created from the set of unknown characters (302) and a second set of pairs of characters is created from the set of known characters (304). A matrix is generated having a plurality of cells, each cell containing a pair of characters. The matrix is interrogated with the first set to generate a first result, and the matrix is interrogated with the second set to generate a second result (302, 304). The first result is compared with the second result (306). A first predetermined action is taken if the first result matches the second result, while a second predetermined action is taken if the first result does not match the second result (308).

31. A method of name recognition, comprising:
-
loading at least one mailpiece onto a scanner;
scanning a mail name and a mail address from the at least one mailpiece;
interpreting a plurality of characters from the mail name;
sending the mail address to a database comprising change of address information;
comparing the mail address with the change of address information;
determining a change of address name from the database, wherein the change of address name corresponds to the mail address and an old address from the change of address information;
creating a first set of pairs of characters from the plurality of characters comprising the mail name;
creating a second set of pairs of characters from the change of address name;
generating a matrix having a plurality of cells, wherein each cell contains a pair of characters;
interrogating the plurality of cells of the matrix with the first set of pairs of characters and generating a first result;
interrogating the plurality of cells of the matrix with the second set of pairs of characters and generating a second result;
comparing the first result with the second result;
printing a new address from the change of address information on the at least one mailpiece if the first result matches the second result; and
sending the at least one mailpiece downstream for further processing if the first result does not match the second result.

32. An apparatus for recognizing alphanumeric characters, comprising:
-
a scanner for imaging a set of unknown characters;
a memory device comprising a database including a set of known characters; and
a processor, wherein the processor;
generates a first set of pairs of characters from the set of unknown characters and a second set of pairs of characters from the set of known characters;
generates a matrix having a plurality of cells, wherein each cell of the plurality of cells contains a pair of characters, interrogates the plurality of cells of the matrix with the first set of pairs of characters to generate a first result and interrogates the plurality of cells of the matrix with the second set of pairs of characters to generate a second result;
compares the first result with the second result; and
takes a first predetermined action if the first result matches the second result and a second predetermined action if the first result does not match the second result. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
