Correlation function (statistical mechanics) — For other uses, see Correlation function (disambiguation). In statistical mechanics, the correlation function is a measure of the order in a system, as characterized by a mathematical correlation function, and describes how microscopic variables… … Wikipedia
Phase correlation — In image processing, phase correlation is a fast frequency domain approach to estimate the relative translative movement between two images. Method Given two input images g a and g b:Apply a window function (e.g., a Hamming window) on both images … Wikipedia
Phase transition — This diagram shows the nomenclature for the different phase transitions. A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter… … Wikipedia
Correlation sum — In chaos theory, the correlation sum is the estimator of the correlation integral, which reflects the mean probability that the states at two different times are close: where N is the number of considered states , ε is a threshold distance, a… … Wikipedia
Correlation integral — In chaos theory, the correlation integral is the mean probability that the states at two different times are close: where N is the number of considered states , ε is a threshold distance, a norm (e.g. Euclidean norm) and … Wikipedia
Cross-correlation — In signal processing, cross correlation is a measure of similarity of two waveforms as a function of a time lag applied to one of them. This is also known as a sliding dot product or sliding inner product. It is commonly used for searching a long … Wikipedia
Wigner distribution function — The Wigner distribution function (WDF), named after Eugene Wigner, was first proposed for corrections to classical statistical mechanics in 1932 by Eugene Wigner. But the Wigner distribution function is also a good transform for time frequency… … Wikipedia
Ursell function — In statistical mechanics, an Ursell function or connected correlation function, is a cumulant of a random variable. It is also called a connected correlation function as it can often be obtained by summing over connected Feynman diagrams (the sum … Wikipedia
Triple correlation — The triple correlation of an ordinary function on the real line is the integral of theproduct of that function with two independently shifted copies of itself: int { infty}^{infty} f^{*}(x) f(x+s 1) f(x+s 2) dxThe Fourier transform of triple… … Wikipedia
