| The essay aims at the deep research of the fingerprint identification arithmetic on the basis of the classical model analysis, with the purpose of improvements on the fingerprint identification rate as well as accuracy. The research is about three links of preprocessing, feature extraction and feature matching. It proves the utility value via those ways such as the analysis and comparison of the classical arithmetic, and the improvements acquired from both the practical requirements and applicable examination system. Thus it optimizes the fingerprint identification arithmetic and promotes the accuracy rate.I.D identification provides the research background from the educational examination system. Currently existing method identifies students manually by checking their student-identity-cards, with obvious defect of practice fraud. So as to solve the phenomena the research is on the fingerprint identification arithmetic and software development, to meet the technological needs of students'identification and practice fraud reduction.The research is first on the fingerprint identification arithmetic of the existing classic model-with three links of pretreatment, feature extraction and feature matching, to make improvements on fingerprint identification rate and accuracy. And on this basis combined with the analysis and comparison of the classical arithmetic, the accuracy improvement is reached from the practical application of the examination system, and optimized from system parameter adjustments. Design considerations are focused on system general structure, software structure and database structure. The practical application proves the fingerprint identification arithmetic as utility and action, at the mean time it hoists capacity of identifying rate and accuracy.Educational examination system informationization and practice fraud reduction are the remarkable application effects of the fingerprint identification technology. The survey on the whole fingerprint identification arithmetic contributes to the relating theoretical research, and the arithmetic liability is corrected by practical application. The performance shows the satisfaction of both design and educational examination needs, which enables the system functions accurately and timely. |
