  abstract = {A lot of Non-Photorealistic Rendering methods have been proposed
              for creating an artistic image from an image. In this paper, we
              propose a method for creating colored pencil style images. The
              feature of colored pencil drawings is that, though colored pencil
              drawings are drawn with limited number of colors of pencils, we
              can express a lot of colors and gentle textures by changing the
              strengths when drawing strokes and by overlapping strokes of
              different colors. In order to realize this feature, we determine
              which colors of pencils to use and how deep to push the pencils
              (equivalent to the strength when drawing strokes), then draw
              several types of strokes, such as strokes for outlines, basecoats,
              and shading, allowing the strokes to overlap each other. When we
              create strokes for shading, we make their directions to align
              along the boundaries of regions, resulting in images that are more
              like drawings made by human.},
