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… WebAug 8, 2024 · We obtain the correlation coefficient (a.k.a. the Pearson product-moment correlation coefficient, or Pearson’s correlation coefficient) by dividing the covariance of the two variables by the product of their standard deviations. Mathematically, it looks like this: The values of the correlation coefficient can range from -1 to +1.
