The Centered Discrete Fourier Transform and a parallel implementation of the FFT
This paper describes a novel method for the computation of the Discrete Fourier Transform (DFT). The development of a truly centered DFT is coupled with a method for computing the...

Periodic Plus Smooth Image Decomposition
When the Discrete Fourier Transform of an image is computed, the image is implicitly assumed to be periodic. Since there is no reason for opposite borders to be alike, the “peri...
