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
first develop a novel method for constructing a smooth direction field that
preserves the flow of the salient image features. We then introduce the
notion of flow-guided anisotropic filtering 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. |
