Autocorrelating a Radon Transform

Started by honwingh January 11, 2006
Hi all, I am doing a digital fingerprinting project and I am stuck on
how to perform a normalized autocorrelation on a radon transform could
anyone on this forum help me please?

I have literally taken the radon transform of the image which returns R
and xp matrices, then apply xcorr2 to R...the computation takes over 4
minutes and I need to log map it though it returns warning log of zero. Thanks in advance!
