I am little bit confused over these two. As per my understanding, spatial domain is the usual method we did in matlab by using the function fft2
, which will return a complex value for each pixel. What about temporal? If it is a sequence of images, how do I obtain the 'temporal Fourier domain'?
If you looking at the image, is it true that the temporal Fourier domain shall have the same shape as the spatial domain image (shown in figure is the amplitude of Fourier domain)?
fft
) doesn't care at all. It's just a mathematical operation applicable to vectors (or matrices (fft2
) or tensors (higher-dimensional transforms)) of numbers. $\endgroup$
