This method is called Normalized Correlation Coefficient or Normalized Cross-Correlation (NCC). I looked through OpenCV source code, and then found paper [1] which contains clear description and probably was used in CV_TM_CCOEFF and CV_TM_CCOEFF_NORMED implementation.

Also I found paper [2] which shows promising NCC computation efficiency, but there is no implementation available.
