Abstract

This paper systematically introduces the development of fingerprint recognition technology application status at home and abroad, establishing a fingerprint identification system described the necessity and significance. Based on digital image processing to study the principles and methods of fingerprint identification, the focus of fingerprint recognition algorithm based on neural network, filter and moment invariant fingerprint recognition algorithm and fingerprint matching algorithm, matlab as a simulation tool for the existing three Fingerprint recognition algorithm programming; and various algorithms through experiments demonstrate the advantages and disadva
