Paper Abstract

When we recognize a word JAS in a page of a text by an optical pattern recognition system with a matched spatial filter, we form the filter using the same pattern JAS as a reference object. In the conventional matched spatial filter theory, the word to be detected is regarded as one pattern, therefore, only one autocorrelation peak is given in one identification. In this paper, we propose a new theory for the analysis of an autocorrelation peak signal. On the basis of the multiplexed matched spatial filter theory, we show, in the paper, the analysis of the autocorrelation signal that it is composed of three autocorrelations from 'J', 'A' and '5' and it actually appears in the same position to be superposed.
