MATLAB: IMAGE Processing with FFT

fftimageimage processing

Is it possible to make just the face of an image blur and turn into someone elses face using a kernel and fast fourier transform?
So far I got the entire image to blur with FFT. what modifications, add ons do i have to do?
thank you

For example:
N = 20;             %steps
FFT1 = fft2(Image1);
FFT2 = fft2(Image2);
delta = (FFT2 - FFT1) ./ N;
for K = 0 : N
  IM3 = ifft(FFT1 + K * delta);
  image(real(IM3));
  pause(2);
end
