I had a quick glance on OpenCV-2.1.0-win32-vs2008.exe, but I'm not
familiar with cmake, and couldn't quite find out how the octave
wrappers are supposedly being built (I thought I might just manually
do this).
They provide dlls, import libs and include files, but all in msvc style.
There are older versions of octave bindings at
http://octave-swig.sourceforge.net/octave-opencv.html
These use gnu makefiles for building, so I tried to mimic this
with OpenCV 2.1.0, but mkoctfile/g++ fails with quite a number of
undeclared symbol errors - duh.
I also tried recreating the nnn_wrap.cpp files from the opencv-2.1.0
sources using swig, but here swig stops with a syntax error in its
own libraries/headers ?!?
Ok, so much for a quick-and-dirty tryout.
