Identifying recognition zones by using fingerprints
Datacap uses fingerprints to identify incoming pages. For each incoming page, Datacap generates a fingerprint file that describes the page, and compares the new fingerprint to a fingerprint library for known page types. When Datacap finds a match, it assigns the corresponding page type
The fingerprint library has a second purpose, which is to identify the position of each field for each known page type. There can be many variants of each page type and the position of each field is different for each variant. So you must identify the recognition zones for each variant.
