Abstract: Since its introduction in 1965 by Cooley and Tukey, the Fast Fourier Transform (FFT) has revolutionized signal processing, converting time domain data into frequency domain data with ...

Abstract: The classical method of numerically computing the Fourier transform of digitized functions in one or in d-dimensions is the so-called discrete Fourier transform (DFT), efficiently ...

Image analysis includes changing the characteristics of an image to improve its visual information. However, images are constantly polluted with external and internal noise environments during the ...

This task involves manipulating images by converting them to grayscale, altering and recombining RGB components, and structuring visual layouts. Batch processing techniques are applied to automate ...

When James Cooley and John Tukey introduced the Fast Fourier transform in 1965, it revolutionized signal processing and set us on course to an array of technological breakthroughs. But today’s ...

The linear canonical transform (LCT) is a versatile integral transform that generalises classical transforms such as the Fourier, fractional Fourier, and Fresnel transforms. By utilising four ...

If you do any electronics work–especially digital signal processing–you probably know that any signal can be decomposed into a bunch of sine waves. Conversely, you can generate any signal by adding up ...
