FEATURE NORMALIZING CIRCUIT

摘要

PURPOSE:To realize a character recognizer with a high-speed and simple circuit constitution, by performing simultaneously both the counting and normalization with use of a fixed memory and an adder circuit. CONSTITUTION:The size of a character circumscribing frame of an input character pattern is set to a character width register 2 and a character height register 3. When a feature (i), where (i) is a feature number, is supplied to a feature input 1, the contents of an address (i) of a feature memory 6 and read out. The contents of the address (i) are added with the contents of an ROM which is designated for address by th registers 2 and 3 through an adder 5 and then written again into the memory 6. This process is repeated by times equivalent to countings of feature by giving a scan to a feature pattern register produced by extracting the feature. An integer part of the contents of the final address (i) of the memory 6 is equal to the result of normalization of the feature (i).
