Dear Jesper,
Thank you very much for your time and your nice comments. Actually, I am
comparing some registration methods and I am just trying to find out that
applying registration in a masked region may improve the accuracy of
alignment. It seems that when we have a masked area, the nonrigid
registration would act better than when we have a non masked region
provided we have enough intensity variation. Am I right?
Thanks,
Siamak Yousefi
