    Image Warping Using Few Anchor Points and Radial Functions
    (Blackwell Science Ltd and the Eurographics Association, 1995) Arad, Nur; Reisfeld, Daniel
    Transformations based on radial basis junctions have proven to be a powerful tool in image warping. In the present work we decompose these transformations into linear and radial terms, and show examples where such a decomposition is advantageous. Locally supported basis functions are introduced. Several applications are demonstrated, and a comparison with other warping techniques is carried out. Finally, some fine points of image warping are discussed.
