Separate object from image in matlab

Hi,

I stuck at my study now.

I have one example image.

 From this image, I would like to required to remove:

-the roof -the window -the door -the wall -the smoke bay

by creating an appropriate mask and multiplying it with the Fourier Transform of the image.

How can I do this? I tried to searched from other tutorial but none of them able to help me. I need your help please.

I am looking forward to hear from you. Thank you very much.

I'd probably use morphology with wisely chosen structuring elements. Attached is an FFT demo that reduces ripples in a file. Adapt as needed.
