Paper Abstract

The paper describes how, given a ridge-and-valley image of a fingerprint, a flow map can be extracted. The first step is a unique grayscale algorithm based on 3D mathematical morphology to extract the ridge lines under a wide range of conditions. The paper then compares the results of finding the ridge flow using micropatterns, extended templates (on binary and grayscale images), and several well-known, traditional techniques. The question of spatial resolution is also addressed.
