Abstract

PURPOSE:To increase the accuracy of pattern identification section, by the constitution that only the special pattern not discriminated at the discrimination circuit is identified at the pattern identification section. CONSTITUTION:The pattern detection section 12 makes detection and cut-out of the pattern through the horizontal and vertical projection of quantitized pattern image. When the output of the quantization circuit 11 judges the pattern, the discrimination circuit 13 discriminates if the pattern is the special symbols like comma or period, and if it is the special symbol, the result of discrimination is fed to the control section 16. On the other hand, the symbol discrimination is disable as the result, the circuit 13 transfers the pattern image to the pattern recognition section 14, where the identification by means of the matching method is made with the reference pattern in the reference pattern memory 15, and the result is fed to the section 16. Thus, accurate identification can be made to any deformed pattern, allowing to increase the accuracy of the pattern identification section.
