Original ticket http://projects.scipy.org/numpy/ticket/1714 Reported 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

Since this is new functionality, you should ask on the mailing list whether this can be included.

A unit test is necessary, doctests are not executed by default in the test suite.
