Calculating colocalization of three colours [message #66692]

Hi all,

say I have two images, r(ed) and g(reen), and I want to know how
colocalized these colours are. I do c1=correlate(r,g). if c is close
to 1 then there is a lot of colocalization, if c~0 then there is none,
if c~-1 then some joker just gave me the same image twice, inverting
one of the copies! (usually, one calculates c on a ROI...)

I am trying to figure out how to do something similar when a b(lue)
image is added to the mix. I could do them pairwise, but that means
for each set, I would end up with three numbers...

Any ideas?

Many thanks,
Gianguido
