Abstract
Mosaicking in biometrics is a topic of great interest among researchers these days, since it is an important step towards solving the problem of security of data. This paper presents design and implementation of Mosaicking algorithm. This technique is beneficial for providing authentic access as well as security to the biometric image template. We have designed an algorithm for fingerprint mosaicking in order to achieve the required performance. The proposed algorithm provides the effective solution of security issues regarding biometrics techniques without affecting the fingerprint quality. Results discussion section depicts the efficacy of proposed algorithm.
Highlights
A fingerprint based verification system consists of two different stages: i) the enrolment stage where the fingerprint images acquired and stored in the database
Each set consisting of 10*8 fingerprint images and as a total 320 fingerprint images have been incorporated during system testing
This research describes and discusses the mosaicking process in order to improve the quality of fingerprint images
Summary
A fingerprint based verification system consists of two different stages: i) the enrolment stage where the fingerprint images acquired and stored in the database. Solid state sensors widely used these days in various applications as commercial, financial and many more. These sensors sense the limited amount of ridges and furrow those there on a fingertip. Limited amount of information can be extracted from these fingerprints in comparison to the information extracted from elaborated fingerprints In this scenario the matching performance of the fingerprint verification system is being affected since the small overlap region between the query template and stored template results in fewer corresponding points and increases the false rejection or may accept the false image
