How do I perform the following steps in MATLAB:

- Covert Image to Gray

- Resize image to 1024 by 1024

- Find the DFT of image

- Plot phase angle of the transform

- Plot spectrum of the transform

- Reconstruct original image using only phase information

i.e. set F(u,v)=1 and then find the IDFT

- Reconstruct original image using only spectrum information

i.e. set the exponential term to 1 (or theta=0)
