FingerMatcher.compareTemplateRecords Method

Module: FingerMatcher

Definition

Compares two template records and outputs a score.

The score is normalized to take into account the number of fingers/views inside each record

compare_template_records(self, reference_record: FingerTemplateRecord, probe_record: FingerTemplateRecord, trust_filled_positions: bool) -> int

Parameters

reference_record FingerTemplateRecord
in Reference template record.

probe_record FingerTemplateRecord
in Probe template record.

trust_filled_positions bool
in If True, template(s) of one position in reference will be compared only to the templates of the same position in probe. If False, all templates in reference will be compared to all templates in probe (this method is also known as ‘flat’ comparison).

Returns

int
Comparison score, in the range 0 to 65535.
See FingerMatcherThreshold to set a threshold to take a match/no-match decision.
