Please excuse me if the following question looks too dumb:
So, I would like to implement the simplest intensity-based 3D rigid body within-modality registration (6 parameters), just like between the volumes of an fMRI scan, for a real-time application. I checked the ITK source and saw things like fixed image, moving image, etc. within the registration examples. The example source was declaring objects using classes and all was done using classes as one might expect.
HOWEVER, I would like to get ALL the way down to the C++ implementation so that I can cherry-pick only the minimal amount of code and insert it into my application. In other words, I need to access the source of all those classes so that I can go more C-like rather than C+±like. I searched for CPP files within the source folder “InsightToolkit-5.0.1”, but it seems this returns mostly the higher-level examples that call the classes.
In this respect, could you let me know how I can get to the C++ source of the classes?
Thank you very much.
