[Insight-users] Newbie question about getting a sub-image from an Image object

[Anja Ende]

Hi everyone,

Is there a filter in ITK that I can use that returns a sub-image of a given
image object.

What I have is an itk::Image object that has 4D data (3D over time). Now,
what I wanted to do is query this object and get volumes at individual time
points out and use them with VTK.

Is there a simple filter with which I can achieve this? So, the resulting
image from the filter would basically be 3D.

Cheers,

Anja
