[Insight-users] Internal pixel type

[Luis Ibanez]

Hi Paolo,

Thanks for you precise question.

When you use the NormalizedCorrelation metric, you don't need to
convert the images to float. It should be fine to keep your images
as unsigned short, since this metric internally uses the NumericTraits
in order to find the types that appropriate for accumulating
and for performing floating point operations.


    Regards,


        Luis
