Thanks Jim
I made a matching algorithm with R, but I get good results for two images of the same person, so I use a cross correlation function to directly compare images. Do you know of normalized cross-correlation function with R?.

Hi Bernado

I need to compare two fingerprint images and let me know if you can do
with R. I have used the technique of minutiae but it seems to work
better with the cross-correlation and wanted to know if you can do with R.

Hi Juan,
If you're using minutiae, you will want something like character recognition to identify the (admittedly arbitrary) elements of fingerprints like loops and whorls and their relative extents and positions. I don't know whether there is much character recognition stuff done in R, but it would certainly be related.
