Repositions the quadrants of the fft image, so that the zero frequency components of the fft are at the center of the image. This is useful for visualizing the Fourier transform.
Function
CuviStatus fftShift(const CuviImage& src,
CuviImage& dst,
const CuviStream& stream = CuviStream());

Example
//Creating GPU images
CuviImage input = cuvi:io::loadImage(path), fftImage, fftShifted;
//Computing the Fourier Transform
cuvi::imageTransforms::fft2(input,fftImage);
//Shift the fft
cuvi::imageTransforms::fftShift(fftImage, fftShifted);
