Image Quilting for Texture Synthesis and Transfer Alexei A. Efros1,2 William T. Freeman2 1University of California, Berkeley 2Mitsubishi Electric Research Laboratories Abstract We present a simple image-based method of generating novel vi- sual appearance in which a new image is synthesized by stitching together small patches of existing images. We call this process im- age quilting. First, we use quilting as a fast and very simple texture synthesis algorithm which produces surprisingly good results for a wide range of textures. Second, we extend the algorithm to per- form texture transfer – rendering an object with a texture taken from a different object. More generally, we demonstrate how an image can be re-rendered in the style of a different image. The method works directly on the images and does not require 3D information. Keywords: Texture Synthesis, Texture Mapping, Image-based Rendering 1 Introduction In the past decade computer graphics experienced a wave of ac- tivity in the area of image-based rendering as researchers explored the idea of capturing samples of the real world as images and us- input images quilting results ing them to synthesize novel views rather than recreating the entire physical world from scratch. This, in turn, fueled interest in image- Figure 1: Demonstration of quilting for texture synthesis and tex- based texture synthesis algorithms. Such an algorithm should be ture transfer. Using the rice texture image (upper left), we can syn- able to take a sample of texture and generate an unlimited amount thesize more such texture (upper right). We can
