[Insight-users] How to down resample 3D image

[Luis Ibanez]

Hi Ted,

Please post more information.

There is no much help that we could provide
base solely on the content of your email.        :-/


Please post:


   - Input Image Information
      - Origin in mm
      - Orientation (direction cosines)
      - Spacing in mm
      - Number of pixels along each dimension
   - Output Image Parameters
      - Origin in mm
      - Orientation (direction cosines)
      - Spacing in mm
      - Number of pixels along each dimension
   - Your source code
      - We can't tell what is wrong in
      your code if we can not see it   :-)


You may find useful to look at the multiple examples of
resampling described in the ITK Software Guide

      http://www.itk.org/ItkSoftwareGuide.pdf

and the associated source code in the directory

       Insight/Examples/Filtering/
ResampleImageFilter.cxx
ResampleImageFilter2.cxx
ResampleImageFilter3.cxx
ResampleImageFilter4.cxx
ResampleImageFilter5.cxx
ResampleImageFilter6.cxx
ResampleImageFilter7.cxx
ResampleImageFilter8.cxx
ResampleImageFilter9.cxx
ResampleOrientedImageFilter.cxx
ResampleVolumesToBeIsotropic.cxx
SubsampleVolume.cxx


BTW: You don't need to crop the images in order to resample them.


   Please post the information above,


        Thanks


             Luis
