1. How does correlation integral of two functions represent their similarity and why convolution integral does not? I mean how does integration of a shifted function with another show their correlation and similarity?
Shouldn't we subtract the square of two functions to find their difference and similarity?
2. And what is the relation between "correlation coeff." in probability theory and "correlation integral" in signal processing?
(Thank you, all!)
