A Novel Fingerprint Reconstruction by Using Four Concrete Schemes of Pattern Matching to Enhance Accuracy Fields
Subscribe/Renew Journal
Fingerprint system use in the pixel system for interacting to the problem of many fields. In this fingerprint system has generally represented by four schemes:grayscale image, phase image, skeleton image, and minutiae scheme which are used in this paper to find out spurious minutiae in the fingerprint. Most of the fingerprint reconstruction schemes has been existed which based on converting minutiae representation to phase (continuous phase and spiral phase). But this still contain a few spurious minutiae especially in high curvature region. For a direct use of the existing reconstruction algorithm to a latent fingerprint in NIST SD27. Both the ridge flow and minutiae in the reconstructed fingerprint match the original fingerprint well. But, apparently, the reconstructed ridge pattern does not match the original ridge skeleton exactly. This novel reconstruction method proposed the difficult and important problem of latent fingerprint restoration using significantly modified existing reconstruction algorithm to make the reconstructed fingerprints appear visually more realistic, brightness, ridge thickness, pores, and noise should be modeled. The accept rate of the reconstructed fingerprints can be further enhance by reducing the image quality around the spurious minutiae in the grayscale image and other features (such as ridge orientation and skeleton) manually marked by the latent expert.
