Hi,
I need to use a function like Matlab's Normalized 2-D cross-correlation (normxcorr2):
http://www.mathworks.com/help/images/ref/normxcorr2.html
in order to do template matching between an image and a template. I only found alglib::corrr1d which is 1-dimensional and not normalized. Could someone point me if there's another function I can use, or an easy way to modify the code to do this?

I'm trying to implement a Matlab prototype in C++ or C#, and this is the only library I found with a cross correlation function.

Thanks!
Eli
