This software is taken verbatim from the OpenCV (http://sourceforge.net/projects/opencvlibrary/).

I don't know who wrote the routine cvMatchTemplate, but it is exceptional code and deserves recognition. All I've done
|
|
is write a Matlab MEX interface, and provide the routine separately from the OpenCV library. My motivation
|
|
for doing this was simply to make it more accessible. The OpenCV is bloated and poorly documented -- two negatives
|
|
which make it confusing and inconvenient for many people to use, despite the fact it contains many excellent features.
|
|
It seems that providing this code meshes well with the OpenCV's aim for widespread use, but if I've
|
|
violated the license, please indicate so.
|
|
|
|
Anyway, I hope this interface to the OpenCV code is beneficial to someone. I was frustrated by the lack of fast
|
|
NCC code available on the net -- many claim to have written fast routines, but don't readily share them. In my
|
|
experience this far, the OpenCV routine is the fastest general purpose, exact way to do NCC ou there. There are
|
|
domain-dependent speed-ups, which I discuss at www.cs.ubc.ca/~deaton/remarks_ncc.html. You may find my remarks there
|
|
useful.
|
|
|
|
I'd be interested to hear about your own NCC experiences,
|
