[Insight-users] Buffered Regions

[Sergio Vera]

Hello Vikash,

If you fill the iterator with RequestedRegion or Buffered Region you will
end (usually) with an iterator that moves over the whole image.
If you want your iterator over the small region you need to link it with
the region defined in the step 3 that you have just described.

Regards
