Fast Fourier Transform (FFT) - MATLAB & Simulink Introduction DFTs with a million points are common in many applications. Modern signal and image processing applications would be impossible without an efficient method for computing the DFT. Direct application of the definition of the DFT (see Discrete F
2-D fast Fourier transform - MATLAB fft2 - MathWorks - MATLAB and Simulink for Technical Computing This MATLAB function returns the two-dimensional discrete Fourier transform (DFT) of X. ... Description Y = fft2(X) returns the two-dimensional discrete Fourier transform (DFT) of X. The DFT is computed with a fast Fourier transform (FFT) algorithm.
Interplay of fft, ifft, fftshift, and ifftshift in MATLAB | Reflections The confusion resolved All of the above makes sense, once we realize that fftshift and ifftshift do not have any deep connection with fft2 and ifft2 functions. They exist only to apply circular shifts in opposite directions. And one does need these shifts

MATLAB Central - Steve on Image Processing » Fourier transforms The time domain (or spatial domain for image processing) and the frequency domain are both continuous, infinite domains. There is no explicit or implied periodicity in either domain. This is the one I call the Fourier transform. The time domain is ...
