Abstract:
This paper presents a non-photorealistic rendering technique that automatically generates a line drawing from a photograph. We aim at extracting a set of coherent, smooth, and stylistic lines that effectively capture and convey important shapes in the image. We ?rst develop a novel method for constructing a smooth direction ?eld that preserves the ?ow of the salient image features. We then introduce the notion of ?ow-guided anisotropic ?ltering for detecting highly coherent lines while suppressing noise. Our method is simple and easy to implement. A variety of experimental results are presented to show the effectiveness of our method in producing self-contained, high-quality line illustrations.
