Intelligent brush strokes

Published: 05 August 2012 Publication History

Abstract

We present a fully automatic brush stroke placement algorithm for non-photorealistic rendering leveraging importance sampling techniques. Smarter brush placement enables creation of images using only a handful of well-placed strokes, avoiding the "textured" look common to prior techniques. We focus on the problem of converting source images to painterly renderings, but our technique could be extended to work on video source material or to generate abstract paintings without any source imagery. We leverage genetic search algorithms to evaluate the quality of the final images, guiding the solution through the large space of potential images.
