Fingerprint images are textural images consisting of ridges and valleys. The orientation of textures can be determined by orientation field computation. Fingerprint orientation field is the critical basis for fingerprint image segmentation, filtering enhancement and matching processes, and the fingerprint orientation field algorithm plays a very important role in the applied Automated Fingerprint...
Data classification problem is a flourishing research field. Classification is the process of finding the common properties among different patterns and classifying them into classes. SVM (support vector machine) is one of classifier for solving binary classification problem. In traditional SVM solution algorithms, objective function is a strictly convex unconstrained optimization problem, but is...
Spatial hypersurface plays a very important role in the classification problem. In SVM, classification hypersurface is emphasized because of the direct induction of the support vectors, so the hypersurface reflecting the relation between categorical attribute and condition attributes acquired by SVM promotes the classification effect. In traditional SVM solution algorithms, objective function is a...
