Directional texture transfer with edge enhancement
Texture transfer re-renders a target image with high-frequency information (texture) taken fromparts of a reference image that is matched locally to the target image using characteristics such as color. In this paper, we add a directional factor based on the ﬂow of the target image, creating a stroke-like effect that follows edgesmore accurately. In addition, we propose amethod to clearly express object boundaries by considering the effect of the medium on edges in the reference image. We also show how to select an appropriateweight for this directional factor fromthe reference image.We demonstrate the suitability of this improved formof texture transfer for expressing various artistic styles, and compare our resultswith those from previous texture-transfer algorithms. We ﬁnd that our algorithm can be adapted to texture synthesis as well.
