[Insight-developers] feature matching recomendations?

[Richard Beare]

Hi,

Just wondering whether anyone had recommendations for implementation
of correlation type  feature matching. I'm interested in the standard
type of thing - normalised cross correlation between a neighbourhoods
centred on each  feature. There will be lots of pairs of features for
which the correlation must be calculated. There seem to be a couple of
options - adapting the registration metrics, using
NormalizeCorrelationImageFilter which doesn't seem to be quite right
for the purpose, or writing something new. Are there any other
alternatives?

Thanks
