[Insight-users] ITK_USE_OPTIMIZED_REGISTRATION_METHODS

[michiel mentink]

Hi Luis,

I tried compiling with enabled Review but the registration algorithm then
crashed with
all kinds of buffer overflows etc, so I reverted back to 'normal'.

I will try again soon as I'm also trying to get a debug and release version
of itk running.

I don't really have any plans with a GPU, I'm just looking at different
possibilities of
speeding up the registration.

cheers, Michael
