This paper describes the realtime image processing features in the Xerox DocuTech document processing system. The image processing features offered include image enhancement, halftone screen removal (de-screening) with an FIR low pass filter, and an image segmentation algorithm developed by Xerox, which can be used for documents with text and high frequency halftone images, such as pages from typical magazines. The image segmentation algorithm uses a modified auto correlation function approach to detect halftone areas on the document. With this set of image processing features, it is possible to handle a wide variety of input documents on the scanner, and generate high quality output prints.
