[ITK-users] [ITK] region of interest size problem

[Dženan Zukić]

Hi Oscar,

the output dimension is the same: 3D input produces 3D output, 2D input
produces 2D output etc. But the point of RoI filter is to get an image
which is only a part of the input image, and in that respect the filter is
working correctly. What did you expect to happen? If you want only part of
the image be processed, set its RequestedRegion to something smaller than
LargestPossibleRegion.

Regards,
Dženan
