Make sure you get OpenCV 2.0 (not earlier versions)
Ubuntu Karmic includes only opencv 1.x. You probably want to use opencv 2.0. There is a package for this in the Humanoids Lab APT repository. If you're on fairly recent i386 hardware, it should work.
- Repo: deb http://www.prism.gatech.edu/~ndantam3/apt nth main
- Package: opencv2
- Install prerequisites. On ubuntu, this is apt-get install build-essential python-dev libgtk2.0-dev libopenexr-dev libpng12-dev libtiff4-dev libjasper-dev octave
- ./configure && make && make install
For Win32 systems
- Ignore this link, can be found in Willow Garage link below //Precompiled OpenCV libraries and headers
Download Visual Studio 2008 - Get VS2008 from MSDN alliance.
Download OpenCV - Grab the binary installer here. Accept default configurations. Choose the checkbox for "Adding to System PATH."
OpenCV Help - Help with OpenCV install
Willow Garage Instructions - Add the CV (include / binary) paths to Visual Studio's configuration settings. Do a test project in VC++ (or your language of choice).
