    Finger Print Analysis and Matching Using Fuzzy Logic Design

    Fingerprint authentication is implemented using many algorithms, which are based either on minutiae analysis or non minutiae analysis. Preprocessing of the fingerprints is important for better accuracy. Preprocessing includes segmentation and noise removal, which are considered two major steps in preprocessing. In this paper segmentation is performed by using fuzzy...
