A Comparative Study on Paper Currency Recognition and Identification Using Image Processing Techniques

Abstract

Almost all the countries across the world today have their own individual currency systems for different denominations. Various features that accompany these currencies like images, logos, watermarks, serial numbers, textures, font styles etc., tell them apart from each other. These features at the same time can be used for counterfeit currency production, which if not put a check on, can become a threat to any nation’s economy. In this paper we have tried to review the currencies of various countries, their markers and features and the algorithms and techniques used to recognize and authenticate them.
