Definitions for "Autocorrelation"
The correlation between data in one part of an image or at one time and that at another. The spatial autocorrelation in an image can be measured by Fourier Transforms and Variograms.
The correlation of a variable with itself over successive time intervals.
The autocorrelation of an object , known as the Patterson map in crystallography, is the correlation product of with itself: A • A . By the convolution theorem, the Fourier transform of the autocorrelation of is the squared Fourier modulus of : F( A • A ) = F(A)* F(A) = |F(A)| 2. The autocorrelation is therefore an equivalent way of representing Fourier modulus data.
