# fouier transformation in python open cv

f = np.fft.fft2(img) fshift = np.fft.fftshift(f) fshift = np.fft.ifftshift(fshift)

**Here is what the above code is Doing:**

1. fft2: Compute the 2-dimensional discrete Fourier Transform.

2. fftshift: Shift the zero-frequency component to the center of the spectrum.

3. ifftshift: The inverse of fftshift.
