[R] compare two fingerprint images

[Juan Antonio Gil Pascual]

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?.
