Adjusting Level of Abstraction for Stylized Image Composition

Recently, many image stylization techniques have been proposed to convert photographs into illustrations, paintings, cartoons, etc. Artists sometimes use these techniques to efficiently generate background images for their own illustrations of foreground objects, such as cartoon characters. However, this approach often produces unnatural results because the level of abstraction between the foreground and the background images are different, resulting in inconsistent atmosphere between them. In this paper, we address this problem and propose a method for adjusting the abstraction level of the stylized background images. The effectiveness of our method is demonstrated by several examples with different levels of abstraction.
