Cross correlation integral
In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is commonly used for searching a long signal for a shorter, known feature. It has applications in pattern … See more For continuous functions $${\displaystyle f}$$ and $${\displaystyle g}$$, the cross-correlation is defined as: If $${\displaystyle f}$$ and $${\displaystyle g}$$ are both continuous periodic functions of period See more In time series analysis and statistics, the cross-correlation of a pair of random process is the correlation between values of the processes at … See more Caution must be applied when using cross correlation for nonlinear systems.

Webof cross-correlation is very similar to that of convolution. Mathematically, the main difference is that when two functions are cross-correlated, neither function is time-reversed before being shifted and compared. Cross-correlation ∫ ∞ −∞ f _ g = f (τ)g(t +τ)dτ Convolution ∫ ∞ −∞ f ∗ g = f (τ)g(t −τ)dτ WebCross-correlation can track objects that deform over time, but with obvious and significant qualifications that will not be discussed here. Cross-correlation can also easily track a feature that moves by a significant fraction of its own size across frames, whereas this amount of translation could put a snake outside of its basin of convergence.
