Parameters
- person
- Type: SourceAFIS.Simple..::..Person
Person object to use for template extraction.
Remarks
Extract(Person) method takes Image from every Fingerprint in person and constructs fingerprint template that it stores in Template property of the respective Fingerprint. This step must be performed before the Person is used in Verify(Person, Person) or Identify(Person, IEnumerable<(Of <<'(Person>)>>)) method, because matching is done on fingerprint templates, not on fingerprint images.
Fingerprint image can be discarded after extraction, but it is recommended to keep it in case the Template needs to be regenerated due to SourceAFIS upgrade or other reason.
