METHOD OF RECOGNIZING A SYMBOL ON A BANKNOTE AND A COPROCESSOR FOR A COMPUTING SYSTEM OF A BANKNOTE PROCESSING DEVICE Russian patent published in 2019 - IPC G07D7/206 

FIELD: data processing.

SUBSTANCE: group of inventions relates to a method of recognizing symbols on banknotes and a coprocessor of a computer system of a banknote processing device, which enables to implement said method. In the method of character recognition, scanning a banknote to obtain a digital image consisting of pixels, for which membership in a certain class is determined, based on said class, the location of the symbol to be recognized is determined, character locate predefined shape and size matched with the symbol image, wherein binarization is carried out to extract pixels associated with the symbol. Coprocessor for the banknote processing device computing system comprises an input port for obtaining pixel values corresponding to the character locate, where said value defines either a pixel of a symbol, or a pixel of a space, a decision logic circuit configured to provide a set of numerical characteristics for each verification character locate and an output port for issuing sets of numerical characteristics corresponding to character locate string lines.

EFFECT: technical result consists in broader possibility of using method for recognizing characters of any type of font.
