Customer Notation Detection

< Back

The Customer Notation Detection ("CND") feature of DocuTran II provides automated mark detection from image of pre-defined areas of a document. DocuTran currently uses CND to detect change of address, read votes on Proxy forms, verify existence of signatures, and detect customer written messages on remittance forms.

The CND feature’s exclusive, patent pending detection algorithms are fast, accurate and flexible.

• Complex remit sized documents can usually be fully processed at track speed on suitable transports at speeds up to 600 documents per minute. For other image enabled transports or for very complex forms, CND can be implemented as a background process.

• Tangent uses skew adjustment and speed adjustment algorithms to accurately locate the detection areas even from imperfect document images.

• The algorithms provide for zones of individual boxes, groups of boxes (where only one box in a group should be marked,) signature areas and “presumed blank” note zones. A form can contain up to 200 mark boxes, 20 groups and 200 note zones. The product provides results that can be tailored to the needs of the individual processing shop.

The automated detection process supports change detection in preprinted portions of the document, such as the mailing address, blank areas and in write-in zones provided for customer entry of changes. The preprinted zones may include other printing like postal bar codes and the write-in zones may include underlining and prompting words. In both cases the CND detection algorithms can detect and ignore the extraneous information, avoiding the most common causes of false detection.

CND’s direct benefits include:

• significant improvement in detection accuracy
• dramatic labor savings over pre-sorting by operators at mail openers

DocuTran supports a CND correction keying mode to handle the confirmation of ambiguous marks. The correction keyer is automatically directed to documents where the intent of the customer could not be determined. The operator simply clicks the mouse in the appropriate box to indicate the correct value.
