We investigated machine learning-based joint banknote recognition and copyright detection method.Unlike existing methods, since the proposed method simultaneously recognize banknote type and detect copyright detection, it is significantly faster than T-Shirt existing serial banknote recognition and copyright detection methods.Furthermore, we propose an explainable artificial intelligence method for visualizing regions that contributed to the recognition and detection.Using the visualization, it is possible to understand the behavior of the trained machine learning system.
In experiments using the United State Wooden Dolls Dollar and the European Union Euro banknotes, the proposed method shows significant improvement in computation time from conventional serial method.
