Abstract: The method may be used in the devices for banknote detecting, counting or sorting; it may be used to determine the banknote main characteristics: its currency type and denomination. The method is based on a computational processing of the banknote digital image formed in the device during scanning. Increase in the banknote processing speed is the technical result. The first variant of the method envisages a preliminary classification and further checking of correspondence to selected possible classes according to several criteria typical for each particular class. For checking of correspondence, an admissibility of the value of interrelation characteristic for two areas is validated. According to the second variant, there is made classification on the base of a banknote digital image and for each possible class the measure of the banknote correspondence to the image is calculated and used for ranking, the banknote is referred to the class closest to it by the measure of correspondence.

Abstract: The invention relates to banknote verification devices that work using transmitted light. The claimed device has the technical result of uniformly illuminating the banknote that is being tested. The device comprises radiators (1), radiation receivers (3) situated on the opposite side of a banknote (2), and a light guide (4) which is situated between the radiators and the tested banknote and which is designed in the form of a tetrahedral prism with a trapezoidal base. One of the parallel side faces of the light guide (4) used as a radiation inlet face is oriented towards the radiators, while the opposite outlet face is oriented towards the surface of the banknote, all the other faces being light reflecting. The radiators (1) are disposed along the inlet face of the light guide (4) with equal intervals therebetween so that the sections of the outlet surface illuminated by adjacent radiators overlap.
