On the topology preservation of Gneiting's functions in image registration
Chiara Bosica, Roberto Cavoretto, Alessandra De Rossi +1
The purpose of image registration is to determine a transformation such that the transformed version of the source image is similar to the target one. In this paper we focus on lan…
RBF-PU Interpolation with Variable Subdomain Sizes and Shape Parameters
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione
In this paper, we deal with the challenging computational issue of interpolating large data sets, with eventually non-homogeneous densities. To such scope, the Radial Basis Functio…
Hermite-Birkhoff Interpolation on Arbitrarily Distributed Data on the Sphere and Other Manifolds
Giampietro Allasia, Roberto Cavoretto, Alessandra De Rossi
We consider the problem of interpolating a function given on scattered points using Hermite-Birkhoff formulas on the sphere and other manifolds. We express each proposed interpolan…
Partition of unity interpolation using stable kernel-based techniques
R. Cavoretto, S. De Marchi, A. De Rossi +2
In this paper we propose a new stable and accurate approximation technique which is extremely effective for interpolating large scattered data sets. The Partition of Unity (PU) met…
Efficient computation of partition of unity interpolants through a block-based searching technique
R. Cavoretto, A. De Rossi, E. Perracchione
In this paper we propose a new efficient interpolation tool, extremely suitable for large scattered data sets. The partition of unity method is used and performed by blending Radia…
