Yemeni Paper Currency Detection System

With the great technological advances in colour printing, duplicating and scanning, counterfeit notes haves posed an increasing threat to currency markets all over the world. Over the past few years, the Yemeni currency market has suffered extensively from this problem. Although the Yemeni Paper Counterfeit- Currency Detection System (YPCDS) has made steps to counter this problem, it is limited to the 1000 denomination, leaving a considerable chance for counterfeiting other dominations. This paper offers a technical remedial solution to this problem for all denominations using image processing and machine learning techniques. The main aim of this system is to create an automatic system robot to recognize and detect Yemeni paper currency genuine or counterfeit. The system framework consists of five phases: acquisition of the currency image, preprocessing, feature extraction, classification, and verification. MATLAB is the main program for creating this system. The efficacy of the system was tested experimentally using four Yemeni currency categories and the system was found to be able to detect whether currency is genuine or counterfeit with high accuracy and fast processing time.
