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. In certain circumstances, which depend on the properties of the input, cross correlation between the input and output of a system with nonlinear dynamics can be completely blind to … See more • Tahmasebi, Pejman; Hezarkhani, Ardeshir; Sahimi, Muhammad (2012).

Invariant Target Detection in... WebOct 31, 2024 · Before we get into some theory, it is important to note that in CNNs although we call it a convolution, it is actually cross-correlation. It is a technicality, but in a CNN we do not flip the filter as is required in typical convolutions. However except for this flip, both operations are identical.
