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)
