Abstract: In this paper, we propose a banknote simulator that generates aged and soiled banknotes. By analyzing the characteristics of circulating banknotes, we developed Gaussian brightness models for gray level changes of circulating banknotes. In addition, the Perlin noise model was used to simulate soiling. The proposed algorithm was tested using US Dollars (USD) and the experimental results show that the proposed method effectively simulated soiled banknote images from new banknote images.
