'''Tutorial Session on ITK''' (Luis Ibanez)

= Topics =
*How do you efficiently integrate VTK and ITK with respect to reading and writing images?  Is there one class that can be used to hold data sets for both libraries?
*How to do FFTs in ITK?
*What type of coordinate space should be used, voxels vs. real space?
*What type of image formats should be used?
*Is there any standard way to read in coefficient files, i.e., algorithm specific parameters?
*How are XML/MRML files parced in ITK/VTK? We want to know how to use the vtkXMLparser and MRML objects to parse our XML files.
*What are the memory and performance issues with ITK?
*How can we debug memory leaks (or force memory collector to start collecting)?
*How can I access the metadata of each slice in a 3D DICOM volume?

= Hands On =

* ITK - VTK Integration

* FFT
** Insight/Examples/Filtering/
*** FFTDirectInverse.cxx
*** FFTDirectInverse2.cxx
*** FFTImageFilter.cxx

* Voxels vs Real Space
** Real Space
* File Formats
** Depends on the purpose...
*** MetaImage
*** Analyze
*** DICOM
*** Nrrd
* Standard for reading coefficients
** Not really...
** It is worth to define one
* XML/MRML Parsing
** Need help from Steve Pieper here (Jim? Alex? Laurent?)
* Memory issues in ITK
** Many Trade offs
** Usually trading computation time versus memory
** ITK only supports shared memory, not distributed memory (MPI)
