Abstract
Official abstract text for this publication.
Systems, methods and computer-readable media that facilitate matching biometric data to entries in a gallery of biometric data. According to embodiments, a method is provided to match a query comprising biometric data to zero or more of the entries in the gallery. According to this method, a match query is received. The entries in the gallery of biometric data can then be filtered using features of the biometric data to produce a subset of entries that excludes unlikely matches to the query biometric data. A set of candidate entries can be created from the subset of entries where the candidate entries are high probability matches to the query biometric data above a certain pre-determined threshold.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of matching biometric data to entries in a gallery of biometric data, comprising: receiving a match query comprising query biometric data; generating a target code from the query biometric data contained in the match query; filtering the entries in the gallery of biometric data by comparing the entries to the target code in order to produce a subset of entries that excludes unlikely matches to the query biometric data; filtering the entries in…
