  abstract = {We present an interactive system for creating pen-and-ink-style
              line drawings from greyscale images in which the strokes of the
              rendered illustration follow the features of the original image.
              The user, via new interaction techniques for editing a direction
              field, specifies an orientation for each region of the image; the
              computer draws oriented strokes, based on a user-specified set of
              example strokes, that achieve the same tone as the image via a new
              algorithm that compares an adaptively-blurred version of the
              current illustration to the target tone image. By aligning the
              direction field with surface orientations of the objects in the
              image, the user can create textures that appear attached to those
              objects instead of merely conveying their darkness. The result is
              a more compelling pen-and-ink illustration than was previously
              possible from 2D reference imagery.},
