Abstract

Threshold modulation has been shown to produce strong effects in error diffusion images. In particular a threshold modulation that is proportional to the input image induces edge enhancement in the output error diffused image. In this paper, examples are shown for image- dependent threshold modulation incorporated into error diffusion implemented on a non- standard raster, such as a serpentine raster or a space filling curve. The amount and type of edge enhancement induced is shown to vary for different raster directions.
