Dependent packages, wrappers, users, and citations¶
Here we list packages that depend on or wrap FINUFFT, and papers or groups using it. Papers that merely cite our work are listed separately at the bottom. Please let us know (and use github’s dependent package link) if you are a user or package maintainer but not listed, and please “star” our GitHub repo.
Packages relying on FINUFFT or cuFINUFFT¶
Here are some packages dependent on FINUFFT (please let us know of others, and also add them to github’s Used By feature):
SMILI, very long baseline interferometry reconstruction code by Kazu Akiyama and others, uses FINUFFT (2d1, 2d2, Fortran interfaces) as a key library. Akiyama used SMILI to reconstruct the famous black hole image in 2019 from the Event Horizon Telescope.
sinctransform: C++ and MATLAB codes to evaluate sums of the sinc and sinc^2 kernels between arbitrary nonuniform points in 1,2, or 3 dimensions, by Hannah Lawrence (2017 summer intern at Flatiron).
fsinc: Gaute Hope’s fast sinc transform and interpolation Python package.
FTK: Factorization of the translation kernel for fast 2D rigid image alignment, by Rangan, Spivak, Andén, and Barnett.
DISCUS: Fraunhofer diffraction from atomic clusters, nanomaterials and powders, by Reinhard Neder and others. Their manual explains that FINUFFT enabled a two orders of magnitude speed-up.
NWelch: Code for estimating power spectra and other properties of non-equispaced time-series, by astronomer Sarah Dodson-Robinson and others.
Picsou: package for solving linear inverse problems with convex penalties using proximal optimization algorithms, in Python, by researchers at EPFL. This includes regularized imaging problems.
Other wrappers to (cu)FINUFFT¶
FINUFFT.jl: a julia language wrapper by Ludvig af Klinteberg, Libin Lu, and others, now using pure Julia, and fully featured (rather than via Python). This is itself wrapped by AbstractNFFTs.jl in NFFT.jl.
TensorFlow NUFFT: a wrapper to the differentiable machine learning Python tool TensorFlow, for the CPU (via FINUFFT) and GPU (via cuFINUFFT). By Javier Montalt Tordera (UCL).
JAX bindings to FINUFFT: a wrapper to the differentiable machine learning Python tool JAX. Directly exposes the FINUFFT library to JAX’s XLA backend, as well as implementing differentiation rules for the transforms. By Dan Foreman-Mackey (CCA).
Research output using (cu)FINUFFT¶
Marco Barbone has used FINUFFT and cuFINUFFT to accelerate 4D MRI reconstruction via the XD-GRASP algorithm by 11x. See their 2021 conference paper.
