Abstract

High-performance classifiers derive from an hierarchical scheme to balance accuracy and precision. From practice in intelligent license-plate readingwe discuss how the accuracy can be raised using a heterogeneous set of intelligent modules. Further we introduce an extension of the Akaike theorem to set the decision threshold for optimal precision. This allows for a real-time reading that has identified more than 85\% of the passing cars with a 0\% false acceptance during 2 weeks in March 1999 on a highway near Utrecht (The Netherlands).
