Fatigued bills have harmful influence on daily operation of Automated Teller Machine (ATM). To make the fatigued bills classification more efficient, development of an automatic fatigued bill classification method is desired. In this paper, we propose a new method to estimate fatigue levels of bills from feature-selected acoustic energy pattern of banking(More)
