We present in this paper a technique for synthesizing virtual woodcutsbased on real images. Woodcuts are aancient form of art in which an image is printed from a block of carved wood. Our solution is fully automatic, but it also allows a great deal of user control if desired. Given an input image, our solution will synthesize an artistic woodcut from this image. Previous work on this topic has mainly relied on simulation of the actual physical interaction process between wood, ink, and paper, whereas we present a consistent solution based on four steps: image segmentation, computation of orientation fields, generation of strokes, and final rendering. Although some non-photorealistic rendering work could be possibly extended to approximate woodcut effects, ours is the first consistent approach targeting woodcuts specifically for images. We illustrate the potential of the proposed technique with examples of virtual woodcuts, obtained either automatically or user guided.
