A practical box spline compendium

M Kim, J Peters - Applied Mathematics and Computation, 2024 - Elsevier
Box splines provide smooth spline spaces as shifts of a single generating function on a
lattice and so generalize tensor-product splines. Their elegant theory is laid out in classical …

A box spline calculus for the discretization of computed tomography reconstruction problems

A Entezari, M Nilchian, M Unser - IEEE transactions on medical …, 2012 - ieeexplore.ieee.org
B-splines are attractive basis functions for the continuous-domain representation of

FastSpline: Automatic generation of interpolants for lattice samplings

J Horacsek, U Alim - ACM Transactions on Mathematical Software, 2023 - dl.acm.org
Interpolation is a foundational concept in scientific computing and is at the heart of many
scientific visualization techniques. There is usually a tradeoff between the approximation …

A geometric construction of multivariate sinc functions

W Ye, A Entezari - IEEE Transactions on Image Processing, 2011 - ieeexplore.ieee.org
We present a geometric framework for explicit derivation of multivariate sampling functions

Voronoi splines

M Mirzargar, A Entezari - IEEE Transactions on Signal …, 2010 - ieeexplore.ieee.org
We introduce a framework for construction of non-separable multivariate splines that are
geometrically tailored for general sampling lattices. Voronoi splines are B-spline-like …

Towards an unbiased comparison of CC, BCC, and FCC lattices in terms of prealiasing

V Vad, B Csébfalvi, P Rautek… - Computer Graphics …, 2014 - Wiley Online Library
In the literature on optimal regular volume sampling, the Body‐Centered Cubic (BCC) lattice
has been proven to be optimal for sampling spherically band‐limited signals above the …

[HTML][HTML] Volume reconstruction based on the six-direction cubic box-spline

H Kim, M Kim - Graphical Models, 2023 - Elsevier
We propose a new volume reconstruction technique based on the six-direction cubic box-
spline M 6. M 6 is C 1 continuous and possesses an approximation order of three, the same …
