Hi Huanxiang,
The itkResampleImageFilter works fine for subsampling an image.
It is actually one of the examples in the Insight/Example/Filtering
directory.
Please look at:
Insight/Examples/Filtering/
SubsampleVolume.cxx
You simply need to use the itkIdentityTransform, keep the origin
and orientation, while chanching the output image spacing and the
output image size (in pixels)
That being said,
you could also use the filter
itkShrinkImageFilter

Regards,
Luis
