Image Interpolation with Geometric Contour Stencils [PDF]
We consider the image interpolation problem where given an image vm,n with uniformly-sampled pixels vm,n and point spread function h, the goal is to find function u(x,y) satisfying vm,n = (h*u)(m,n) for all m,n in Z.

On a geometric approach to the estimation of interpolation projectors
Suppose $\Omega$ is a closed bounded subset of ${\mathbb R}^n,$ $S$ is an $n$-dimensional non-degenerate simplex, $\xi(\Omega;S):=$ min {$\sigma\geqslant 1: \Omega\subset \sigma S$}.

High Accuracy Geometric Hermite Interpolation [PDF]
In natürlicher Verallgemeinerung der Hermiteschen Standardinterpolation werden für parametrisierte ebene Kurven interpolierende kubische Splines p(i) bestimmt. Dabei sind die Knotenpunkte und in jedem Knotenpunkt Tangente und Krümmung vorgeschrieben. Die Komponenten von p(i) sind kubische Polynome auf den Parameterintervallen \((i,i+1)\).

Geometric Estimates in Interpolation on an n-Dimensional Ball
Suppose \(n\in {\mathbb N}\). Let \(B_n\) be a Euclidean unit ball in \({\mathbb R}^n\) given by the inequality \(\|x\|\leq 1\), \(\|x\|:=\left(\sum\limits_{i=1}^n x_i^2\right)^{\frac{1}{2}}\).

Fractal interpolation-based micro-surface reconstruction method for composite pore walls
The pore wall morphology of carbon fiber reinforced composite (CFRP) laminates is one of the key factors to determine their service performance. However, due to the direction angle of the material fibers, the original micro surface morphology of the pore

Use of interpolation methods for modeling the stress-strain state of operated oil storage tanks
The aim of the research is the comparison of two approaches for computer modeling of the stress-strain state of thin-walled shells of engineering structures, considering the imperfections of the geometric shapes arising due to their operation. The object
