The Fast Fourier Transform (FFT) is a fundamental building block used in DSP systems, with applications ranging from OFDM based Digital MODEMs, to Ultrasound, RADAR and CT Image reconstruction ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Efficient implementation of the Radon Transform using the Fast Fourier Transform (FFT) and the Fourier Slice Theorem in Python, with a Tkinter-based GUI for interactive usage. The Radon Transform is ...

Abstract: Factoring a matrix and multiplying successively by the factors can sometimes be used to speed up matrix multiplications. This is, in fact, the trick which creates the fantastic gains of the ...

Abstract: Fast Fourier transform (FFT) correlation is compared with direct discrete time (DDT) correlation of complex signals in terms of number of operations and memory requirements. The results ...

This paper introduces FlashFFTStencil, a memory-efficient stencil computing system designed to bridge FFT to fully-dense stencil computations on TCUs. Aimed at bound shifting, FlashFFTStencil ...

Hamamatsu Photonics has launched the most compact Fourier Transform-near infrared (FT-NIR) spectrometer engine currently on ...
