A new open-source C++ library called FFTM brings portable distributed 3D and 4D fast Fourier transforms to CUDA and HIP multi ...

The fast Fourier transform, forward and inverse, has found many applications in signal processing. Although the theory of fast Fourier transforms is well-known, numerous commercially available ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

In Chap. 6 we saw that the discrete Fourier Transform (DFT) could be used to perform convolutions. In this chapter we look at the computational requirements of the DFT and derive some fast algorithms ...
