Currently, there Is a growing demand for automated teller machine (ATM) in the cities. Due to the large concentration of banknotes, these devices have been targets of theft with the use of explosives. When this action occurs, generally, the ATM dyes the banknotes using a degradation agent in order to avoid the use of banknotes in the market and helps the police to identify criminals. In this article, we propose a dyed banknotes detection system using digital image processing tools. In the experiments performed to test images 72 and five systems, we found that the results are excellent with respect to detection error and the runtime.
