How to normalize an image to zero mean and unit variance - verylijing - Sep 22 7:38:25 2008



Good everyone,
I am working on face recognition. I need your help on how to normalize 
an image to zero mean and unit variance in MATLAB. In addition, I will 
also appreciate simple explanation on it.
 
Thank you very much.
