ABSTRACT:
In order to recognize confusable characters exactly, a pattern recognition system is described wherein, when more than two reference patterns having a similarity to the input unknown pattern larger than a predetermined threshold level are detected by a first discriminating circuit, one or more suitable feature comparators are selected from a plurality of feature comparators by the control signals corresponding to the reference patterns or the category thereof detected by the first discriminating circuit and the selected one or more feature comparators determine the identity of the input unknown pattern by comparing selected features thereof to the corresponding portions of the plural reference patterns under consideration.
