abstract = {The correct display of edges in halftoned images is necessary for
accurate image reproduction. This problem has been addressed by
preprocessing the image to enhance the edges or by altering the
halftoning algorithm to account for edges. In this paper we
present a postprocessing edge enhancement technique that is
applicable to all halftoning algorithms. We identify two types of
edge pixels in the image dark and light edge pixels. Edges in an
image are highlighted by setting the dark/light edge pixels to
black/white. We tested our method on a modern laser printer.
Because of this our evaluation of the technique is restricted to
clustered halftoning methods. We evaluated the effect of enhancing
edges by conducting a user survey to determine the perceived value
of the different edge enhancement methods. The results of the user
survey - while not statistically significant - indicate that our
postprocessing technique achieves comparable results to previous
edge enhancement methods. Our technique is simple to implement and
can be applied to any halftoning technique and thus is a good
default edge-enhancing approach},
