I read Friston, Ashburner, et. al. 1995 "Spatial Registration and
Noralization of Images", the re-alignment algorithm works when displacement
is small (smaller than the smoothness of the image). Theoretically you can
blur the image enough to make SPM align it for you. But I was wondering if
SPM would do this blurring and going down in scale-space for you. How does
SPM do it and how well does SPM do it as the displacement grows?
I am interested in the intra-modality case.
