title: OpenCV: Normalizing pixel values of an image
body: <p>I am trying to normalize the pixel values of an image to have a mean value of 0.0 and a norm of 1.0 to give the image a consistent intensity. There is one OpenCV function, i.e. <code>cvNormalize(src,dst,0,1,cv_MINMAX)</code>, but can this function be used for my purpose? Any help is appreciated. Thank you.</p>
