Image Correlation to quantify crack growth

[Lakshmikantha, M. R.]

Hi all,
I have been using ImageJ for analysis of Cracking in drying materials
(soil). I am trying to quantify the crack growth taking one image (un
cracked) with a image sequence (several images taken at different stages of
crack growth).
I tried to use the plugins to correlate, but they can do with staks or
images of equal number. Now, is there is any other plugin or method where
in i can fix one image as the reference and correlate the rest of the
images sequencially.

thank you all in advance.
