Correlation

[hchemis]

I have two images (A1 and A2) and I want to know the correlation with the other one. I tried converting the images into 8 bit and then used the correlate (under FD Math) but did not work. Can anyone help me with this ?

A quick google search gives several option: https://www.google.co.uk/search?q=imageJ+image+correlation&gws_rd=cr&ei=xpnfWKfpD6aLgAbjiInACQ#spf=1

Good day,

the problem with your post is that you don't tell us what doesn't work.

"FD Math"b computes the "Correlation Function" of two images and
actually it only computes the inner part of it, because the correct
Correlation Function has a larger support.

However, I guess you wish to compute the "Correlation Coefficient" of
two images. If this is indeed the case, then you must multiply the two
images (Image Calculator) and finally get the mean of the resulting
product image (Measure).
