2.1.2 Cross-correlations The cross-correlation function (CCF) is a way of analyzing the similarity between two time series as a function of the displacement in time of one related to the other. The CCF is built with the cross-correlation coefficients, that is, the correlation coefficients bet...
For example, consider this 2-D cross-correlation: X = ones(2,3); H = [1 2; 3 4; 5 6];% H is 3 by 2C = xcorr2(X,H) C = 6 11 11 5 10 18 18 8 6 10 10 4 2 3 3 1 TheC(1,1)element in the output corresponds toC(1–3,1–2) =C(–2,–1) in the defining...
In all cases, the correlation has a maximum value of one at zero lag (i.e., no time shift) since when the lag (τ or ℓ) is zero, this signal is being correlated with itself. It is common to normalize the autocorrelation function to 1.0 at lag 0. The autocorrelation of a sine ...
