A couple of other references: http://www.owlnet.rice.edu/~elec431/projects96/pictomaniacs/previous.html - explains the relation of cross-correlation to convolution; this is part of http://www.owlnet.rice.edu/~elec431/projects96/pictomaniacs/DSP.html - a tutorial on digital signal processing applied to pattern matching.

Gosi - how is your image pattern recognition going? This is a subject in which I'm interested. I just now came across a couple of references I found when looking into this: http://www.mathworks.com/products/demos/image/cross_correlation/imreg.html- a step-by-step tutorial in recognizing embedded images using Matlab http://students.ee.sun.ac.za/~riaanvdd/image_processing_tools.htm - link to a method called the Fourier-Mellin transform http://www.idiom.com/~zilla/Work/nvisionInterface/nip.html - "Fast Normalized Cross-Correlation" by J. P. Lewis of Industrial Light and Magic (the famous animation studio) A good phrase on which to search is: "normalized cross-correlation".
