Spline Interpolation and Smoothing on the Sphere

SIAM Journal on Scientific and Statistical Computing, 1981
Motivating his study by some need of the analysis of meteorological data the author solves the following extremal problems: A) minimize the functional \(I_ m(u)\) subject to \(u(P_ i)=z_ i\), \(i=1,...,n\), where \(\{P_ i\}\) are points on the sphere and \(I_ m\) is a natural analogue on the sphere of the functional \(\int^{2\pi}_{0}[u^{(m)}(\theta ...

Multivariate Smoothing and Interpolating Splines

SIAM Journal on Numerical Analysis, 1974
A theorem that characterizes spline functions that both smooth and interpolate is given. A bivariate generalization is presented which permits interpolation and smoothing of information which is not necessarily on a rectangular grid. A theorem which involves reproducing kernels for Hilbert spaces unifies this theory.

Contour Smoothing Based on Weighted Smoothing Splines

2006
Here we present a contour-smoothing algorithm based on weighted smoothing splines for contour extraction from a triangular irregular network (TIN) structure based on sides. Weighted smoothing splines are one-variable functions designed for approximating oscillatory data.

Shape constrained smoothing using smoothing splines

Computational Statistics, 2005
A nonparametric smoothing algorithm is proposed for evaluation of the function \(g:[a,b]\to R\) which minimizes \[ \sum_{i=1}^n (y_i-g(t_i))^2+\lambda\int_a^b (g^{(2)}(u))^2du \] under the constrains \(g^{(r)}(t)\geq 0\), \(\forall t\in[a,b]\). Here \((t_i,y_i)\) are the data points, \(g^{(k)}\) denotes derivatives of \(g\) with respect to \(t\), and \(
