[ITK] [ITK-users] Image conversion from 3D volume to 2D slices

[Dženan Zukić]

If the input and output pixel types are different, extract filter does
simple casting. That causes the effect you have observed. You need to use
RescaleIntensityImageFilter

either
before or after the extract. Have the extract filter use the same input and
output pixel type.
