Cross-correlation - Wikipedia

Webfilter. A cross-correlation (Xcorr) was then conducted between the two channels of low passed data that measured the same axis (i.e., that measured accelerations in the X-axis on the OSI and chassis) for all six pairs of channels collected. The original data set was then shifted by the phase lag between the two data sets, as determined WebA known technique to obtain subpixel resolution by using object tracking through cross-correlation consists of interpolating the obtained correlation function and then refining peak location. Although the technique provides accurate results, peak location is usually biased toward the closest integer coordinate. immunotech oxford

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 different times, as a function of the two … See more Caution must be applied when using cross correlation for nonlinear systems.
