Interpolation with the polynomial kernels

no code implementations15 Dec 2022 Giacomo Elefante, Wolfgang Erb, Francesco Marchetti, Emma Perracchione, Davide Poggiali, Gabriele Santin

We will then study the Reproducing Kernel Hilbert Spaces (or native spaces) of these kernels and their norms, and provide inclusion relations between spaces corresponding to different kernel parameters.

Reducing the Gibbs effect in multimodal medical imaging by the Fake Nodes Approach

1 code implementation21 Feb 2022 Davide Poggiali, Diego Cecchin, Stefano De Marchi

Then we propose a Fake Nodes scheme for image resampling designed to reduce the Gibbs effect when oversampling the functional image.

Oversampling errors in multimodal medical imaging are due to the Gibbs effect

1 code implementation10 Mar 2021 Davide Poggiali, Diego Cecchin, Cristina Campi, Stefano De Marchi

To analyse multimodal 3-dimensional medical images, interpolation is required for resampling which - unavoidably - introduces an interpolation error.
