  abstract = {Most halftoning techniques have been primarily concerned with
              achieving an accurate reproduction of local grayscale intensities
              while avoiding the introduction of artifacts. A secondary concern
              in halftoning has been the preservation of edges in the halftoned
              image. In this paper, we will introduce a new halftoning technique
              that utilizes a bandpass pyramid to achieve an accurate
              reproduction of important attributes in the image. Ink is
              distributed through the bandpass pyramid primarily according to a
              user defined importance function. This technique has three main
              characteristics. First, our technique can produce results similar
              to many other halftoning techniques by allowing a generic
              importance function to be specified. If the chosen importance
              function is average intensity we obtain results similar to
              traditional halftoning. We also show how the importance function
              can be changed to highlight areas with high variance. Second, in
              addition to changing the importance function, the drawing
              primitives can also be changed. By using line segments instead of
              single pixels as drawing primitives we illustrate how edge
              enhancement can be achieved. Third, this technique allows the user
              to easily limit the number drawing primitives used. This is useful
              in limited resource rendering. In addition to providing a
              tailorable halftoning technique our method can easily be adapted
              to produce two tone non-photorealistic (NPR) images. We illustrate
              this by showing how sketched effects can be achieved by aligning
              the drawing primitives according to different image attributes.},
