how to find amplitude and phase spectrum of an input image

given an image I(x), we have: A(f) = ℜ(fft(I(x))), P(f) = ℑ(fft(I(x))), where A(f) and P(f) are amplitude and phase spectrum of given input image. Please give a brief description along with results

The question statement appears to be incorrect. The amplitude spectrum is not the real part of the FFT, and the phase spectrum is not the imaginary part. Also, it is not clear what question you are asking, or what help you need.
