Use Normalized Cross Correlation as similarity measure instead of Squared
Difference...
http://www.mlpedia.org/index.php?title=Normalized_cross_correlation
Citation from that page:
"In computer vision, the normalised cross correlation is used as a
distance metric between image patches, as it gives some invariance to
changes in illumination between the patches."
