Estimate the two-dimensional cross-correlation
returns the cross-correlation of matrices
C = xcorr2(A,B)
B with no scaling.
xcorr2 is the two-dimensional version of
xcorr. It has its maximum value when the two matrices are aligned so that they are shaped as similarly as possible.
is the autocorrelation matrix of input matrix
A. It is identical to
