I still have no idea what you said. The gray scale image is already quantized. Do you want to quantize it in intensity differently? Like into fewer gray levels?

Finding the magnitude of the discrete Fourier transform does not calculate the magnitude of the image: it only finds the magnitude of the frequency components. If you were to quantize the frequency components and then ifft() to get back to an image, I suspect the result would be pretty messy.
