We propose a texture synthesis method to enhance the trackability of a target planar object by embedding natural features into the object in the object design process. To transform an input object into an easy-to-track object in the design process, we extend an inpainting method for naturally embedding the features into the texture. First, a feature-less region in an input object is extracted based on feature distribution based segmentation. Then, the region is filled by using an inpainting method with a feature-rich region searched in an object database. By using context based region search, the inpainted region can be consistent in terms of the object context while improving the feature distribution.
