[Insight-users] Using MultiResolutionImageRegistrationMethod

[Ranjan, Sohan (GE, Research)]

I would appreciate if I could get clarification on the following vis-a-vis 
MultiResolutionImageRegistrationMethod:

1. Does the code uses copies of downsampled images for computation, or 
    image iterators are used smartly for computation?

2. Is it possible to skip levels in registration? 

For example, suppose I have a huge image which is read, but I want to do registration
at the four-times resolution. Can I use an instance of MultiResolutionImageRegistrationMethod 
with, say, 4 levels, and then I do registration only at the extreme coarse level and exit. By doing 
this, I would not need to make an extra copy of the downsampled image.
