A method is studied for deriving the coefficient of correlation ρ between pixels from the DCT coefficient. The simplest way is to derive the pixel values by applying the fast inverse DCT to the DCT coefficients of interest and then to calculate ρ according to the definition in the image ...

The correlation coefficient formula is: r = (n*sumXY - sumX*sum Y)/sqrt{(n*sumX^2 - (sumX)^2)*(n*sumY^2 - (sumY^2))}.The terms in that formula are: n = the number of data points, sumXY is the sum of the product of the x-value and y-value for each point in the ...
A correlation coefficient is a measure that calculates how strong the relationship between two of the variables is. Here is the formula for correlation coefficient: where: r is correlation coefficient n is the number of pairs of data points ...
The complex correlation coefficient of two fully developed speckle fields of different wavelengths is evaluated for two different geometries, and its meaning is discussed in connection with two-wavelength-measurement techniques applied to rough surfaces (e.g., two-wavelength rough-surface interferometry, ...
