QUALITY-BASED TEN-PRINT MATCH SCORE NORMALIZATION

摘要

In some implementations, a system is capable of improving the results of a matching operation by normalizing match scores with respect to quality levels of compared fingerprints and/or attributes of the compared fingerprints. The system initially obtains match data of the matching operation. The match data can include baseline record match scores for a set of reference records that are compared against a search record. The system then uses normalization techniques to normalize the values of the baseline record match scores with respect to, for example, quality levels of the search and reference records, and various attributes of the compared fingerprints, such as fingerprint quality, finger position, and detected fingerprint patterns. The normalized record match scores can therefore be used to more accurately represent the similarity between the search record and the reference records.
