Means and Hermite Interpolation

by Alan Horwitz , 2008
"... Let m2 < m1 be two given nonnegative integers with n = m1+m2+1. For suitably differentiable f, we let P, Q ∈ πn be the Hermite polynomial interpolants to f which satisfy P (j) (a) = f (j) (a), j = 0, 1,..., m1 ..."

Verbs and Adverbs: Multidimensional Motion Interpolation Using Radial Basis Functions

by Charles Rose, Bobby Bodenheimer, Michael F. Cohen - IEEE Computer Graphics and Applications , 1998
"... This paper describes methods and data structures used to leverage motion sequences of complex linked figures. We present a technique for interpolating between example motions derived from live motion capture or produced through traditional animation tools. These motions can be characterized by emoti ..."

On Multivariate Hermite Interpolation

by Thomas Sauer, Yuan Xu - ADVANCES COMPUT. MATH , 1995
"... We study the problem of Hermite interpolation by polynomials in several variables. A very general definition of Hermite interpolation is adopted which consists of interpolation of consecutive chains of directional derivatives. We discuss the structure and some aspects of poisedness of the Hermite in ..."

Trigonometric wavelets for Hermite interpolation

by Ewald Quak - Math. Comp , 1994
"... Abstract. The aim of this paper is to investigate a multiresolution analysis of nested subspaces of trigonometric polynomials. The pair of scaling functions which span the sample spaces are fundamental functions for Hermite interpolation on a dyadic partition of nodes on the interval [0,2π). Two wav ..."

On A Hermite Interpolation By Polynomials Of Two Variables

by Borislav Bojanov, Yuan Xu - SIAM J. Numer. Anal , 2002
"... A problem of Hermite interpolation by polynomials of two variables is studied. The interpolation matches preassigned data of function values and consecutive normal derivatives on a set of points on several circles centered at the origin. It includes Lagrange interpolation as a special case. The uniq ..."

Hermite Interpolation and Sobolev Orthogonality

by Esther M. García-caballero, Teresa E. Pérez, Miguel A. Piñar, I Física, Teórica Computacional , 1999
"... Abstract. In this paper, we study orthogonal polynomials with respect to the bilinear form where (f, g)S = V(f)AV(g) T +〈u, f (N) g (N) 〉, V(f) = (f (c0), f ′ (c0),...,f (n0−1) (c0),...,f(cp), f ′ (cp),...,f (np−1) (cp)), u is a regular linear functional on the linear space P of real polynomials, c ..."
