Abstract: Recent printers, scanners and image manipulation software identify images of currency, will not process the image and display an error message linking to www.rulesforuse.org. The detection algorithm is not disclosed, however it is possible to test sample images as to whether they are identified as currency. This webpage shows an initial analysis of the algorithm's properties, based on results from the automated generation and testing of images.
