Processing Scenario

When the initialization is completed successfully, you can start the document recognition processing. But before, you need to choose and set up the processing scenario.

A scenario is the main setting for Document Reader SDK. It controls all scanning processes of the Core framework and defines the way Core works. The set of available scenarios is different for each Core type. To see which scenarios are supported by certain Core types, visit the Core page.

Features

Different scenarios support different sets of features, below is the full list of available features.

Feature	Description
Visual zone OCR	Optical character recognition of the document visual zone text fields based on document templates included in the database.
Document type identification	Automatic recognition of the document type: no need to manually select a country, document type, and series for processing.
MRZ OCR	Reading and parsing the machine readable zone lines into separate fields.
Barcode recognition	Reading the 1D and 2D (PDF417, QR, Aztec, Datamatrix) barcodes and automatic parsing into text fields using included document template specifications if the template database is available and the document type is identified.
Document location	Detecting the document boundaries and cropping out the document from the supplied picture.
Graphics cropping	Cropping graphic fields, such as a photo portrait and signature, based on templates included in the database.
Checking security features	For each document type, certain secutiry checks can be performed. For example, UV dull paper check, image patterns (VIS), IR transparency, etc. You can find the security checks by document types in the Documents list.
Hologram detection	Automatically determining the location of a hologram and checking the hologram authenticity.
Multipage processing	Processing child documents (second page, back side) if they are identified for the detected document type or if an ID1-sized document is processed.

Setting up

To set the processing scenario, use:

TypeScript

DocumentReader.setConfig({
    processParams: {
        scenario: ScenarioIdentifier.SCENARIO_FULL_PROCESS
    }
});
