  • Texture synthesis and transfer for pixel images
    Patent number: 6919903
    Abstract: The invention provides an image-based method for generating novel visual appearance in a new image. Synthetic texture is stitching together from small patches in existing images. First, we use a least cost path determination to determine the local boundaries between the patches. Second, we perform texture transfer by rendering an arbitrary object with a synthetic texture taken from a different object. More generally, we provide methods for rendering entire images in styles of different images. The method works directly on pixel images, and does not require 3D information.
