While the Raspberry Pi is not exactly a powerhouse, it should be capable of doing some OpenCV image or video processing. Has anyone tried to install it?

Yes, it is possible to install OpenCV on the Raspberry Pi using either Debian Squeeze or Arch Linux ARM. As done in the following two blog posts, it should just be a matter of either installing or compiling.

For prosperity's sake, you need to install opencv via pacman on Arch Linux ARM and compile it on Debian. Like so.

$ wget http://sourceforge.net/projects/opencvlibrary/files/ \
$ make
$ sudo make install

Your biggest problem will be performance though. It seems that OpenCV has a GPU module designed to utilize GPU computational capabilities, though. It is implemented using NVidia's CUDA Runtime API though, so you will need a NVidia GPU in order to utilize the GPU capabilities. For more information, you should read the wiki page.

OpenCV is now available in apt-get. You can search for it:

apt-cache search opencv

If you are doing development, just do:

sudo apt-get install libopencv-dev

At the time of this writing, it is OpenCV 2.3

Its pretty straightforward if you compile every thing on the RPi, I couldn't get a cross compiler to work and the camera/webcam was slow/unresponsive So my answer is yes but . . . depends what you want to do with it :)
