[Insight-users] 2D mask apply to 3D image series

Hi Suyang,

There is no particular filter that comes to mind...

My suggestion will be to use image iterators and
intertwine the 2D loop with the 3D one.

Another option is to do

   - Extract image filter 3D -> 2D
   - MaskImageFilter in 2D
   - PastImage filter to put the slice back

and set this inside a while loop.

It is quite likely that there
are better ways to do it...

Perhaps looking at the code of the paper:

"Slice by slice filtering with ITK
by Gaetan Lehmann

may lead to a cleaner approach.
