  abstract = {Half-toning is the process by which gray-scale images are
              approximated with sets of black and white pixels. The process
              works because our eyes perceive a local average, thus half-toning
              seeks to approximate the local average. Ideally this approximation
              should be accomplished without introducing ``undesirable''
              artifacts. In many situations the stylized display of images is
              desired. Often this stylized display is accomplished by the
              addition of semi-structured artifacts. In current applications the
              designer processes the image using tools provided by some image
              processing package. The resulting image is then half-toned and
              printed. Half-toning these processed images can reduce the visual
              impact of the special effects that have been introduced in the
              image. In this paper we show that the processes of controlled
              artifact introduction and half-toning can successfully be
              combined. By combining these two processes we ensure that the
              printed image is what the designer intended. We present a brief
              overview of the current error-diffusion half-toning techniques. We
              then propose several ways in which artifacts can be introduced to
              the image. This discussion is accompanied by a set of illustrative
              images. In particular, we discuss the introduction of false edges
              and the alteration of the scan pattern. We illustrate these
              techniques with a variety of images. We conclude the paper with a
              discussion on these new half-ioning methods for the generation of
              binary gray-scale textures. In addition to showing how to generate
              these binary gray-scale textures we also show how these gray-scale
              textures can be used to half-tone images.},
