Abstract
A PC-based two-level classifier for fingerprint recognition is presented. Input fingerprint images are preprocessed via Laplacian edge detector and a skeletonization algorithm. The thinned binary image is then classified into one of the four categories of fingerprint via a curve tracing algorithm and a scoring method. Local density of the designated area is then computed for the second-level classification (i.e. within category classification). The proposed method is found to be reliable for a small set of fingerprints
