When a copy of a digital print is made by a digital print station, an artifact is observed in the copy that has a crosshatch appearance. The Crosshatch Detection and Removal Algorithm detects the presence of the crosshatch artifact. If the artifact is detected it is then removed from the image by the application of a notch filter. This report explains how the algorithm works and results are reported on the performance of the algorithm for a test set of over 100 images.
