[Insight-users] Passing a part of the image as a reference

[Arun Kulshreshtha]

hi,

Suppose i have defined an itkImage with some
parameters and I want to 
pass a subimage of  that to some filter
so that only that part of the image is filtered by the
filter. Function 
SetRequestedRegion() is not available in all
filters. Is there a general way of passing  subimage
to a filter in the 
SetInput function itself. One trivial way is
to copy that subimage to another ItkImage but this
will require u to 
allocate extra memory and copying overhead
which i want to avoid. So I need to know how can I
pass subimage by 
reference ??


Regards
Arun
