摘要

Fingerprints are used in various fields for different purposes. A typical fingerprint systems database may consist of millions fingerprint templates. The performance of matching with a large database has been the focus of in the recent research. This paper proposes an efficient database indexing technique using four fast and lightweight effective filters in a circular pattern matching technique [1]. This approach reduces the number of nominated fingerprints before the matching stage by applying the filters on the database gradually. The filtering algorithms used here are robust and fast and are performed in linear time regarding the fingerprints' rotation. The entire approach has been explained in detail in section V. This paper is an extension of the recent paper [2]. The main motivation of the extension is to deal with fingerprint authentication for one to many fingerprint authentication approaches efficiently.
