[Insight-users] Multiresolution registration shrink factors

[David Wikler]

Dear ITK Users,

   I have a question about shrink factors in
multiresolution MI registration.
If we have 2 datasets with different resolution,
is it better to choose shrink factors so each
resolution level registers volume of the approximatly
same image size and voxel size.
For example, if my fixed volume is 256,256,20 and
my moving volume is 128,128,10

Should I preferably choose

4 4 1
2 2 1

as shring factors

instead of for example
2 2 1
2 2 1

Thanks for your help.
