Description
Original ticket http://projects.scipy.org/numpy/ticket/1714 on 2011-01-15 by trac user bubla, assigned to unknown.
Hello,
I have made a patch that extends the correlate function so it can compute normalized cross-correlation now
See [http://en.wikipedia.org/wiki/Cross-correlation#Normalized_cross-correlation the Wikipedia article].
I have added documentation and simple doctest too, of course.
The patch is against the latest master Git
