HI Maarten,
0) How does the Insight Journal works ?
Answer:
http://www.vtk.org/Wiki/ITK_Procedure_for_Contributing_New_Classes_and_Algorithms
In short, yes, you write an article (a technical report, of a couple of
pages)
and add to it your source code, data and parameters.
Any reader of the Journal should be able to get your code and
simply do on it:
cmake .
make
ctest
and obtain the *SAME* results that you describe in your paper
(or technical report).
You may want to take a look at other papers to get a feeling
for the process.
Here is a good model:
http://www.insight-journal.org/browse/publication/318
1) you can convert all the Amira images to 3D ITK images,
Then you check their Z size, and if it is == 1, then you
pass them through the itkExtractImageFilter, get a 2D
image and pass it to a 2D pipeline.
Yes, that means that your application should compile
*BOTH* a 3D pipeline and a 2D pipeline. There is no
much mistery beyond that.
Regards,
Luis
