I've included it into EZminc package (
https://github.com/BIC-MNI/EZminc develop branch )

To compile it all you will have to install minc from
https://github.com/BIC-MNI/minc , minc4itk branch and

https://github.com/BIC-MNI/minc4itk

the program itself is here:
https://github.com/BIC-MNI/EZminc/blob/develop/tools/itk_similarity.cpp
