Stroke-based editing of object structure

ABSTRACT

Recent years have witnessed significant developments of structural image manipulation techniques. Some of these techniques are based on image warping, which stretches image content to satisfy editing constraints. Other techniques are based on texture synthesis, which synthesizes repeated texture to fill the target image domain so that the result resembles the source image. However, it is challenging for both categories of approaches to generate satisfying results when desired object's skeletal structure is far from the original object as shown in Figure 1. In this extended abstract, we present a new structure editing technique that is based on user provided strokes as structure constraints. Users specify a set of strokes indicating the structure of the input object in an image as well as a set of corresponding strokes in the output domain. Then, our method synthesizes the object texture along these strokes according to the direction and position of the corresponding strokes.
