An Improved Algorithm for Enhancing Fingerprint Image Quality

Abstract

With the development of the fingerprint identification system, the application field of fingerprint recognition is more and more extensive, and it has an increasingly greater impact on people's lives. Nowadays, the fingerprint identification system in our lives is everywhere and has become an indispensable part of our lives. It can quickly identify our fingerprint features and then tell us the true identity of the fingerprint information. Therefore, people's research on fingerprint identification systems is gradually deepening. This paper mainly studies the image preprocessing algorithm in the fingerprint recognition system. In the process of fingerprint identification system, the read image must be preprocessed to make the image clearer and less noise, which is convenient for fingerprint recognition and feature extraction. This paper focuses on the fingerprint image enhancement algorithm, based on the Gabor filter design of the empty filler on the fingerprint image preprocessing, based on the reduction of image enhancement, leaving a large number of holes, fingerprint images with fewer false feature points, improve the follow-up feature points. The speed and accuracy of the extraction algorithm.
