Abstract
A method and apparatus for processing the images of fingerprints, whereby aligned images are subjected to a tessellation process, wherein each image is partitioned into a number of regions. Within each region at least one parameter associated with the ridges is measured and stored: the prevailing ridge orientation, the average ridge separation and the phase of the ridges. The data is projected and stored in a multidimensional coordinate system wherein the representations of any two data are separated by an amount corresponding to the dissimilarity of these data.
