Abstract

For feasible recognition having many categories such as Japanese character recognition, fast matching algorithms are necessary because the matching process occupies most of recognition time. In addition, for improving recognition accuracy, the matching process must use more complicated discrimination functions or a higher dimensional feature space, which involves higher computational costs. Therefore, pre-classification is used, which outputs a set of candidate categories to decrease the number of computations of the complicated discrimination functions.
