Bulk region of interest learning
View Patent ↗A system and method for mail processing. A method includes receiving an image of a mail piece, and identifying multiple regions of interest of the image. The method includes determining a classification key for the image based on a plurality of relationships between the multiple regions of interest and identifying a most-changing region of interest of the multiple regions of interest. The method includes processing the mail piece using the identified most-changing region of interest as the recipient address block.
1. A method, comprising:
receiving an image of a mail piece in a mail processing system;
identifying multiple regions of interest of the image by the mail processing system;
determining a classification key for the image based on a plurality of relationships between the multiple regions of interest;
identifying a most-changing region of interest of the multiple regions of interest; and
processing the mail piece using the identified most-changing region of interest as the recipient address block.
2. The method of claim 1 , wherein processing the mail piece includes performing an optical character recognition process on the most-changing region of interest.
3. The method of claim 1 , wherein processing the mail piece includes sorting the mail piece based on the recipient address.
4. The method of claim 1 , wherein identifying the most-changing region of interest includes performing an overlay process between the received image and a stored image that has a corresponding classification key.
5. The method of claim 1 , further comprising performing a binarization process on the image.
6. The method of claim 1 , wherein if a previous mail piece with a corresponding classification key has not already been processed and registered, then the received mail piece image and classification key is registered for future comparisons.
7. The method of claim 1 , wherein the mail processing system stores OCR pre-knowledge and uses the OCR pre-knowledge for processing the mail piece.
8. The method of claim 1 , wherein the identifying step is not performed until a predetermined number of corresponding images have been processed.
9. The method of claim 1 , wherein the identifying step is only performed when processing a bulk mailing batch.
10. The method of claim 1 , wherein processing step is only performed after the preceding steps have been performed on a plurality of mail pieces and classification keys for bulk mailings have been determined.
11. A mail processing system, comprising:
a processor;
accessible memory; and
an imager configured to create an image of a mail piece, wherein the mail processing system is configured to perform the steps of
receiving an image of a mail piece;
identifying multiple regions of interest of the image;
determining a classification key for the image based on a plurality of relationships between the multiple regions of interest;
identifying a most-changing region of interest of the multiple regions of interest; and
processing the mail piece using the identified most-changing region of interest as the recipient address block.
12. The mail processing system of claim 11 , wherein processing the mail piece includes performing an optical character recognition process on the most-changing region of interest.
13. The mail processing system of claim 11 , wherein processing the mail piece includes sorting the mail piece based on the recipient address.
14. The mail processing system of claim 11 , wherein identifying the most-changing region of interest includes performing an overlay process between the received images and a stored image that has a corresponding classification key.
15. The mail processing system of claim 11 , wherein the mail processing system also performs a binarization process on the image.
16. The mail processing system of claim 11 , wherein if a previous mail piece with a corresponding classification key has not already been processed and registered, then the received mail piece image and classification key is registered for future comparisons.
17. The mail processing system of claim 11 , wherein the mail processing system stores OCR pre-knowledge and uses the OCR pre-knowledge for processing the mail piece.
18. The mail processing system of claim 11 , wherein the identifying step is not performed until a predetermined number of corresponding images have been processed.
19. The mail processing system of claim 11 , wherein the identifying step is only performed when processing a bulk mailing batch.
20. The mail processing system of claim 11 , wherein processing step is only performed after the preceding steps have been performed on a plurality of mail pieces and classification keys for bulk mailings have been determined.
