ABSTRACT:
A fingerprint recognition system for extracting minutiae from a fingerprint image. The fingerprint recognition system generates a corrected image from the input fingerprint image by: eliminating incipient ridges/pores from the fingerprint image by using the density pattern of the pixels of ridge lines/valley lines in the direction orthogonal to the length direction of the ridge lines. The minutiae are extracted from the corrected image.
