### Chapter 4: Frequency Domain
- **FFT/DFT spectrum view** shows magnitude, log magnitude, or phase of the image in the frequency domain. Formula: `F(u,v) = DFT{f(x,y)}`. Apply it to a periodic-noisy state with `log_magnitude` to see the noise peaks.
- **Inverse FFT reconstruction** applies FFT then inverse FFT without filtering to demonstrate reconstruction. Formula: `f = real(ifft2(ifftshift(fftshift(fft2(image)))))`.
- **Inverse FFT reconstruction** reconstructs from a previously saved FFT state. Formula: `f = real(ifft2(ifftshift(F)))`.
