Random fractional Fourier transform : stochastic perturbations along the axis of propagation [PDF]
, 1999 The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects on the FRT action of such a medium

Fourier transforming a trapped Bose-Einstein condensate by waiting a quarter of the trap period: simulation and applications [PDF]
, 2006 We investigate the property of isotropic harmonic traps to Fourier transform a weakly interacting Bose–Einstein condensate (BEC) every quarter of a trap period.

Compensation of linear distortions by using XPM with parabolic pulses as a time lens [PDF]
, 2008 We experimentally demonstrate an all-optical all-fiberized scheme that can eliminate linear perturbations in the time domain. The technique relies on performing optical Fourier transforms on distorted signals to move their distortions from the time to ...

Inverted Residual Fourier Transformation for Lightweight Single Image Deblurring
IEEE Access, 2023 Single image deblurring aims to restore a sharp image by removing blurred areas in the single image. Such blurred images are not only visually unpleasant, but cause various problems in many applications like image recognition.

The Graphon Fourier Transform [PDF]
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020 In many network problems, graphs may change by the addition of nodes, or the same problem may need to be solved in multiple similar graphs. This generates inefficiency, as analyses and systems that are not transferable have to be redesigned. To address this, we consider graphons, which are both limit objects of convergent graph sequences and random ...

THE IMAGE REGISTRATION OF FOURIER-MELLIN BASED ON THE COMBINATION OF PROJECTION AND GRADIENT PREPROCESSING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Image registration is one of the most important applications in the field of image processing. The method of Fourier Merlin transform, which has the advantages of high precision and good robustness to change in light and shade, partial blocking, noise ...

SWIFT: Sweep imaging with FOURIER transformation
Journal of Indian Academy of Oral Medicine and Radiology, 2018 Oral cavity is prone to a variety of diseases starting from simple tooth decay to life-threatening carcinomas. Injudicious use of ionizing radiation may increase the exposure of a patient and this has been overcome with the use of magnetic resonance ...
