METHOD FOR DETRMINING DISTANCE METRIC USED IN FINGERPRINT MATHING OF FINGERPRINT SYSTEM BY LEARNING

摘要

PURPOSE: A method for efficiently learning a distance metric through the minimization of a cost function is provided to improve fingerprint recognition performance by learning a distance metric from training data. CONSTITUTION: A training data is composed of the fingerprint of original content and the fingerprint of distorted content. A distance metric is determined through learning in order to improve recognition performance in the use of training data(S200). A parameterized distance metric is generated in a determination procedure of the distance metric. A cost function is generated. The parameter of the distance metric is determined through the minimization of the cost function.
