ABSTRACT:
We present a new family of multistep iterative interpolation schemes and a 4-point high resolution scheme reproducing quartic polynomials. Interpolation requires two steps: a coarse scale interpolation followed by a fine scale interpolation. The interpolants are C1, have good local properties and no additional memory requirement.
