To use forms classification, you must create reading zones on documents and compare the recognition results from these zones with known identifiers of a class of forms. You can also configure a forms classification on the project level if more than one class shares zones.
Reading zones are fixed areas on documents that contain information you want the project to recognize. In BIC context, three different types of reading zones exist – OCR, OMR and bar codes. However, in forms classification context, you can only use OCR and bar code zones.
- OCR The contents of the reading zone are determined using optical character recognition. The textual content of the zone is the result of this process.
- Barcode The contents of the reading zone are determined using bar code recognition. The number of strings represented by the bar code is the result of this process.
