[Insight-users] getting started with ITK[C++ and c# comparision]

[Dan Mueller]

Hi Sarah,

At the moment the only supported (i.e. maintained and tested) C#
wrappers around ITK is SimpleITK:
    http://www.itk.org/Wiki/ITK/Release_4/SimpleITK/GettingStarted#C.23_binary_files

Unfortunately, SimpleITK does not at present support (deformable) registration.

Therefore it seems you will need to delve into C++. Thankfully, due to
good design choices in ITK, you will probably find that the ITK C++
code is not too dissimilar from C#. For example, most pointers are
implicitly taken care of using itk::SmartPointer behind the scenes
(which is actually much better than garbage collection because a
developer knows exactly when memory will be released).

Of course you can Google for C# to C++ guides. Here is one I quickly found:

If you still want to use C# (say for example for UI) then you may
consider using SWIG which will automatically generate PInvoke wrappers
around C++ code for use in any .NET language. For this you will need
to encapsulate your C++ functionality behind a header file, point SWIG
at the header file, and it will generate your C# wrappers.

Finally, if you are only interested in deformable registration, you
may consider using pre-compiled executables such as:
