ABSTRACT:
The present invention provides a method of processing an unknown physical fingerprint for use in a data processing system to verify/identify an unknown fingerprint. The method involves obtaining an unknown fingerprint image that includes images of ridges, binarizing the images of ridges in the unknown fingerprint image, generating an image with fused ridges by expanding the images of ridges in the binarized image, shrinking the image with fused ridges to create a scaled-down image, and masking a first portion of the unknown fingerprint image with the scaled-down image so as to create a modified image of the unknown fingerprint.
