Presentation Transcript
Agenda • System Description • Deployment Status • Bundle Processing • Machine Recognition Characteristics • Sample Image Review (not in handouts) • Federal Register Notice • Future Initiatives
APPS Deployment Status • 74 Machines, 70 sites • First Article Test completed May ‘04 • Deployment from Aug ‘04 to Oct ‘05
Bundle Processing on APPS • APPS uses optical character recognition (OCR) technology to read both OEL and address block information to sort the mail • Current read rates for OEL bundles is around 80% • Read failures occur due to: • The address block is obscured by opaque strapping material • The address block is obscured by opaque shrink wrap • The OCR fails to correctly decode the OEL
Image Capture Gray Scale Image – 5,807Kb OCR decodes Binary Image Binary Image – 201Kb
Clear Strapping Examples Strap flush with surface Strap spaced away from surface
Federal Register Notice • Recommends placing the address label in one of the four corners of the mailpiece • Where the label WILL be covered - Proposed DMM Changes • Clear strapping (less than 70% haze) • Clear shrinkwrap (less than 70% haze) • An optional bundle label: Includes the OEL, the words “OPTIONAL BUNDLE LABEL”, and the City, State, and ZIP Code
OCR Decoding Challenge APPS OCR Result Mis-segmented Characters, not Identified as “*” “SORT” read as “SORF” Due to touching “*”
Future OEL improvements These are NOT in the proposed DMM changes • Add a bar code to the package and / or OEL label • Use of OCR-friendly fonts for OEL data • Add redundant single-character indication of OEL type • Eliminate dashes ( - ) in OEL, which can appear to touch when printed poorly • Separate fill characters with spaces, to eliminate near-touching
APPS Recommended Address Font • Recommendations same as Flats OCR Optimization • Use 10-12 point font size • Recommended Fonts: Arial Lucida FAX Arial Black Lucida Sans Copperplate OCR-A Courier OCR-B MT Courier New SF Sans Serif Helvetica Tahoma • Avoid narrow type & script fonts
