    Abstract

    Anime designers often paint actual sceneries to serve as background images based on photographs to complement characters. As paint- ing background scenery is time consuming and cost ineffective, there is a high demand for techniques that can convert photographs into anime styled graphics. Previous approaches for this purpose, such as Image Quilting [Efros and Freeman 2001] transferred a source texture onto a target photograph. These methods synthesized corresponding source patches with the target elements in a photo- graph, and correspondence was achieved through nearest-neighbor search such as PatchMatch [Barnes et al. 2009]. However, the near- est-neighbor patch is not always the most suitable patch for anime transfer because photographs and anime background images differ in color and texture. For example, real-world color need to be con- verted into specific colors for anime; further, the type of brushwork required to realize an anime effect, is different for different photo- graph elements (e.g. sky, mountain, grass). Thus, to get the most suitable patch, we propose a method, wherein we establish global region correspondence before local patch match. In our proposed method, BGMaker, (1) we divide the real and anime images into re- gions; (2) then, we automatically acquire correspondence between each region on the basis of color and texture features, and (3) search and synthesize the most suitable patch within the corresponding re- gion. Our primary contribution in this paper is a method for au- Tomatically acquiring correspondence between target regions and source regions of different color and texture, which allows us to generate an anime background image while preserving the details of the source image.
