Why is averaging over overlapping regions necessary? #21

Why can't we just do non-overlapping generation without averaging? I presume you have tried and found that averaging gives better results. Is there any intuition or theory for that?

Can you suggest ways to to average and overlap masks? I went through the paper and the codes but I think I missed some important part.
