An Algorithm for Remove False Minutiae using Trace of Ridge Connectivity

Most of the Automatic Fingerprint Identification Systems define the ridge endings and bifurcation points as the minutia for matching. Therefore, the precise extraction of the minutia is critical in raising the efficiency and reliability of the system. The fingerprint images produced through the preprocessing may have the false minutia happened over the process and they can be the factors to decrease the system efficiency This paper suggests the algorithm, which removes the false minutia after extracting the candidate minutia from the thinned binary images of fingerprint images.
