Popis: Stroke-based rendering is one of the major approaches for creating synthetic paintings, but with only a minor attention so far to stereo painting synthesis. In this article, a fully automatic stereoscopic oil-painting synthesis algorithm is proposed, which takes a photograph and a depth map as input, and generates a pair of oil-painting style, stereo-viewable paintings. Common drawbacks of existing stroke-based rendering results are impressions of repetition and flatness due to the regularity of the used 2D stroke patterns. To reduce these impressions, the proposed approach introduces the concepts of a defocused image, a complexity map, a point map, and a direction map. Those maps serve as important references for decision making and thus, are the foundation for the entire painting simulation process. The key feature of making the developed stroke-based algorithm different from others is that it generates a unique 3D brushstroke according to the characteristics of a local image region. This has greatly reduced the undesirable machine-like appearance in the resulting image. Moreover, a comfortable stereo-viewing experience is assured by the proposed stereo painting and hole-filling strategies. Experimental results show that the proposed algorithm is applicable to a wide variety of image subjects and different depth distributions.
