  abstract = {In this paper, we propose a new technique for automatically
              generating pencil drawing from 2D images using line integral
              convolution. Our idea is inspired by the similarity between the
              stroke textures of pencil drawings and the flow textures generated
              with line integral convolution. We succeeded in creating pencil
              drawings with their tone matching that of the original images
              simply by taking the vector field defining stroke directions and
              the white noise images generated by referring to the intensity of
              the original images as the input to the line integral convolution
              algorithm. By employing the texture analysis techniques, we also
              succeeded in automatically orienting strokes in the directions
              that convey the textures of objects appropriately.},
