ABSTRACTThispaper presents an improved fingerprint verification system by involving an improved
fingerprint enhancement stage using a combination of Inverse filtering and Gabor filtering
algorithms with dynamic block size in order to improve image quality in the enhancement
stage. It has been noticed that the computations of the local ridge direction and also the other
enhancement steps are affected heavily by the used block size. Therefore, an attempt has been
made to develop a more accurate approach which dynamically decides the block size. It is
based on the local ridge frequency. This work also introduces a set of directional
morphological filters utilized for preprocessing the binarized image The effect of the
proposed enhancement algorithm on the fingerprint verification system performance has been
tested to fingerprint images from FVC2000 and it shows a promising result.
