Name
corr2 — 2D correlation coefficient
Calling Sequence
c = corr2(imA, imB)
Parameters
- imA, imB
-
imA
and imB
are 2D matrices of the same size.
- c
-
Correlation coefficient, a scalar of class double.
Description
corr2
computes correlation coefficient of two 2D matrices imA
and imB
.
c = sum( (imA-mA).*(imB-mB) / sqrt(sum((imA-mA).^2) * sum((imB-mB).^2))
mA=mean2(imA)
and mB=mean2(imB)
