[Insight-users] slice-wise running of filters

[Luis Ibanez]

Hi Zein,

The ExtractImageFilter is used for this purpose.

It takes your 3D volume, extracts a 2D slice and
then you pass this slice to the actual filter.

NOTE that there is a difference between

   1) extract slice  + process 2D image
   2) process 3D image + extract slice

In particular for all the filters that use neighbor
information.

If you want to get 3D consistent results, you may
want to use the SetRequestedRegion() feature in
order to request a slice from the output.


Regards,


    Luis
