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 recognition, single particle analysis, electron tomography, averaging, cryptanalysis, and neu… how common is a 6 inch girthWeb8 de mar. de 2016 · All correlation techniques can be modified by applying a time shift. For example, it is very common to perform a normalized cross-correlation with time shift to detect if a signal “lags” or “leads” another..
