Exponential spline interpolation

Computing (Vienna/New York), 1969
Piecewise cubic polynomial spline interpolation [3] or smoothing [4] often gives undesirable inflexion points. We describe a spline interpolation method that allows to avoid these inflexion points and contains cubic splines as special case. The method is a generalization of the work in [2].

Lacunary Interpolation by Splines

SIAM Journal on Numerical Analysis, 1973
In 1955, J. Suranyi and P. Turan commenced the study of what they called (0,2) interpolation. By (0,2) interpolation we mean the problem of finding the algebraic polynomial of degree ≤ 2n-1, if it exists, whose values and second derivatives are prescribed on n given nodes.

Quadratic spline interpolator

International Journal of Systems Science, 1996
A simple system is proposed which generates a quadratic spline function interpolating a given discrete-time signal. It works as a D-A converter which is free from phase distortions and whose output is smooth. The output is constructed as two-fold integration of a staircase signal. A kind of sampled data feedback is employed to stabilize the system. Its

Quasi Interpolation With Voronoi Splines

IEEE Transactions on Visualization and Computer Graphics, 2011
We present a quasi interpolation framework that attains the optimal approximation-order of Voronoi splines for reconstruction of volumetric data sampled on general lattices. The quasi interpolation framework of Voronoi splines provides an unbiased reconstruction method across various lattices.

Spline Interpolation and Smoothing on Hyperspheres

SIAM Journal on Scientific Computing, 1994
The authors generalize a result of \textit{G. Wahba} [SIAM J. Sci. Stat. Comput. 2, 5-16 (1981; Zbl 0537.65008)] concerning spline interpolation and smoothing on the two-dimensional sphere. Their generalizations are threefold. Firstly, Wahba's results are extended to arbitrary dimensional hyperspheres.

On Cardinal Spline Interpolation

Computational Methods in Applied Mathematics, 2013
Abstract. In the present paper it is shown that the interpolation problem for multiple knot cardinal splines subject to general interpolation conditions has a unique solution with polynomial growth if the data grow correspondingly provided a certain determinantal condition is satisfied.

Interpolation by Splines on Triangulations

1999
We review recently developed methods of constructing Lagrange and Hermite interpolation sets for bivariate splines on triangulations of general type. Approximation order and numerical performance of our methods are also discussed.

Geodesic Interpolating Splines

2001
We propose a simple and efficient method to interpolate landmark matching by a non-ambiguous mapping (a diffeomorphism). This method is based on spline interpolation, and on recent techniques developed for the estimation of flows of diffeomorphisms. Experimental results show interpolations of remarkable quality.
