发明名称 Method and system for extending binary image data to contone image data
摘要 A method and system converts a binary image into an analog image by first tagging pixels that are part of edges in the digital image and using this tagging information to eliminate such tagged pixels from the digital filtering process. The elimination of such tagged pixels from the digital filtering process substantially eliminates artifacts near the edges, thereby reducing any distraction from the perceived quality of the output image.
