[ITK] [ITK-users] MutualInformationAffine example broken

[Dženan Zukić]

Hi Yanling,

The usual reason for this is that the images do not overlap in image space,
either with the initial transformation or due to divergence of the
registration. If you run it in debug mode, you will have more information.

Regards,
Dženan
