Abstract

The invention discloses a method and a system for identifying and classifying paper money. By utilizing the method and the system, a sample signal degradation model meeting the application requirements is established through using a statistical method by utilizing a large number of existing reliable samples easy to obtain, states of the paper money with brand new color, eight to nine into new color, seven to eight into new color, below seven into new color, varying degrees of soiling, varying degrees of mutilation, varying degrees of cracks and fold existing in regions, then the classifier study is carried out, a to-be-identified sample is classified and identified, and therefore, a classifying result is accurately obtained, and the cost and the efficiency for developing a paper money identifying product are also reduced.

Description

technical field [0001] The present invention relates to the technical field of banknote identification systems, and more specifically, relates to a method and system for identifying and classifying banknotes. Background technique [0002] At present, banknote processing equipment used in the financial field, such as cash recycling machines, banknote sorting machines, etc., has a banknote identification system divided into two main parts: a banknote classification learning system and a banknote identification system. Please refer to the attached figure 1 And attached figure 2 . In the banknote classification learning system, input the banknote sample image to be learned, and output the banknote classification model; in the banknote recognition system, input the banknote sample image to be recognized, through feature extraction, and apply the classification model obtained in the banknote classification learning system , classify the samples and output the final classificati...
