We present our work in progress in the direction of generating realistic, challenging and diverse test data in order to evaluate a banknote checking system. Test image generation can be divided into, firstly, the design and composition of highly diverse patterns to form the digital design of a banknote, secondly, the application of different variations which are caused by ink, paper and physically printing the note and, thirdly, the simulation of the subsequent image acquisition, which includes variations due to banknote transport, illumination, camera optics and electronics. These simulations are based on and compared to scans of demo banknotes. We present initial results in simulation of banknote paper, printing and image acquisition. We demonstrate the approach in an initial investigation on synthetic defect generation and its impact on banknote checking results. Algorithmic validation of checking routines is also demonstrated. First conclusions are drawn and further work is discussed.
