Paper Abstract

Error diffusion has proven to be a very powerful method of producing binary images that are visually similar to the original grayscale images. It has become so popular that many attempts have been made to improve it. In this paper, two modifications to error diffusion, the serpentine raster and threshold modulation, are analyzed from a theoretical viewpoint. The two analyses reveal the origins of the image quality improvements of the modifications and quantify their benefits.
