Abstract
We produce color pencil drawings from photographs using feature strokes to create the salient linear elements of the picture, and hatching strokes to fill areas. Both types of strokes are generated using line integral convolution (LIC). We improve previous LIC schemes by using feature lines to determine the integration direction, and by introducing grayscale noise into each CMY color channel. Our scheme can produce visually pleasing color pencil drawings in various styles.
