This crate aims to provide easy to use 2D spectral transforms for images, such as Fourier (FFT) and cosine (DCT) transforms. By default, only the Fourier transforms are availables. The cosine ...

Abstract: It is assumed here, that some signal samples in the respective period, available for processing digitally by the fast Fourier transform (FFT) procedure for determining spectra of ...

2.3 The Two-Dimensional Fourier Transform (2D-DFT) The 2D-DFT can be thought of as a composition of separate 1-dimensional DFTs. Looking at the equation we define the 2D-DFT for a 2D sample of signal ...

It is now possible to calculate the Fourier transform of an image on your smartphone, thanks to a new app developed by two nanophotonics researchers in The Netherlands. “2D-Fourier” is available for ...

Abstract: We present a method for multidimensional Fourier transform estimation that is characterised by fast convergence rates using low sampling rates. Unlike similar methods reported in research ...

The primary goal of Super-Resolution (SR) is to reconstruct an image of higher quality from an image of lower quality. The Fourier transform helps in this process by recovering lost, high-frequency ...

In this work, two procedures connected to the Fourier multidimensional transform are presented : an algorithm for the image reconstruction from a restriction of its "brightness function", supposed ...

This is the Fourier Transform. You can thank it for providing the music you stream every day, squeezing down the images you see on the Internet into tiny little JPG files, and even powering your noise ...
