To Calculate Normalized cross correlation - RGB image?

c=imread('originalwatermark.bmp');
d=imread('extracted watermark.bmp');

z=c.*d;
z1=sum(sum(sum(z)));

zz=c.*c;
zz1=sum(sum(sum(zz)));

NC=z1/zz1;
disp('Normalized Coralation for First Watermark');
disp(NC);

* Please clarify my doubt, the coding is correct or not?
