Dear FSLers,
I want to assess the quality of the FLIRT registration of different T1
images to MNI152_T1 template. Could you please advise what is a good
numeric metric for the assessment?
I am thinking of the following ones:
1. Sum of mean square error between the registered and the reference
image (this might not be a good one because I found the intensity
scales of the two images are quite different).
2. Determinant of the transformation matrix (I know this has been used
to evaluate local deformations, but large deformation could result in
good registration quality, so this metric is not relevant?)
3. The final cost function value obtained by FLIRT (corrate, mutual
information, etc.) However, flirt doesn't output this information, is
there easy way to get this value?
Any comment on this will be appreciated.
Leo
PS. Congrats to new royal couple ^_^
