Abstract
With the rapid development of science and technology, the traditional access system due to identify ways, speed and performance etc, it is difficult to meet the limit of reliability and safety work requirements. The fingerprint identification technology with convenient, high precision and low cost advantage, has e the concern of the most widely used effective means of identity authentication.
Based on fingerprint identification system access control software is studied, the first part of fingerprint identification system research background, significance and research status is analyzed, and then introduced the principle of fingerprint identification and basic procedures of fingerprint identification algorithm, then studied, including the fingerprint image preprocessing, feature extraction and features, including pretreatment and through the following steps: fingerprint image enhancement, image segmentation, binary, refined and post-treatment. Finally a simple test, the test results proved this method is feasible.
Keywords: fingerprint image preprocessing, fingerprints, feature extraction, feature matching
