We present a fast, non-iterative technique for producing grayscale images from error diiused and dithered halftones. The rst stage of the algorithm consists of a Gaussian l-ter and a median lter, while the second stage consists of a bandpass lter, a thresholding operation, and a median lter. The second stage enhances the rendering of edges in the inverse(More)
