Identification of Counterfeit currency and denomination using Raspberry pi

Abstract: Advancement in technology leads towards many automated systems which are capable of performing tasks without interference of humans. Money deposit machines, automatic ticket machines are one of such automated systems. In such systems it is necessary to identify the counterfeit and denomination of currency automatically. But available automated currency detection system uses computers and other processors which are bulky in size and cost of the overall system is also more. So it is necessary to develop a system which is capable of identifying the denomination of currency for small scale applications. In this paper, the proposed model will automatically identify the denomination and counterfeit of currency using raspberry pi. Identification of counterfeit and denomination is achieved with the help of basic image processing algorithms such as HSV conversion, template matching, aspect ratio identification, dominant colour and feature extraction. Keywords: Counterfeit currency, denomination, HSV conversion, dominant colour.
