I am doing an affine registration using mutual information and I am getting incorrect results when trying to register the MNI atlas 1mm with the vanderbuild database.
The images of the vanderbuilt data base differ from the others because their image have just 25 slices, the head is not scanned completely and their orientation is different.
I also tried others similarity measures, but the result continuous incorrect. So, how can I solve this problem? Is there any way of creating another similarity measure?
