Abstract

A method for the realisation of a multiple matched filter able to detect different characters in successive planes is proposed. It is based on the fact that when registering the filter for each pattern by placing it in a position that is not in the front focal plane then the corresponding correlations will appear also in different planes. An experimental realisation of the method is presented for the recognition of two characters of similar structure.
