[Insight-users] i have a question about reading an image from a file

[Luis Ibanez]

Hi Knoppix,



1) For instructions on how to write a CMakeLists.txt file
    please read the ITK Software Guide

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

   in particular section 2.2.1, "Hello World"

   The CMakeLists.txt file that you need should look like:


     PROJECT(ReadImage)
     FIND_PACKAGE(ITK REQUIRED)
     INCLUDE(${ITK_USE_FILE})

     ADD_EXECUTABLE(ReadImage ReadImage.cxx )
     TARGET_LINK_LIBRARIES(ReadImage ITKIO ITKCommon)


2) Yes, the input image file is 3D, as indicated by the
    line:

    >   const unsigned int             Dimension = 3;

    You will find 3D images at:

     http://public.kitware.com/pub/itk/Data/BrainWeb/

    download and untar the .tgz files.


3) To view the images you can use

      a) ImageViewer (source code in InsightApplications)
         binary for windows in:
http://public.kitware.com/pub/itk/InsightApplicationsBin/ImageViewer.exe

  or

      b) Slicer (www.slicer.org)

or

      c) SNAP (http://www.itksnap.org/)

or

      d) ParaView (www.paraview.org)


4)  The input of this program is any of the image fileformats
     supported by ITK:

        PNG
        JPEG
        TIFF
        Nrrd
        Analyze
        Nifti
        MINC
        DICOM
        MetaImage
        GIPL
        (among others...)




Please read the ITK Software Guide in order,
and follow the exercises with the proposed input
images in Insight/Examples/Data.

That will save you a lot of time.


     Regards,


         Luis
