Computer vision (CV) allows your Raspberry Pi to see things. In practical terms, this means that your Raspberry Pi can analyze an image, looking for items of interest and even recognizing faces and text.
If you link this with a camera to supply the images, all sorts of possibilities open up.
You want to install SimpleCV computer vision software on your Raspberry Pi.
To install SimpleCV, first install the prerequisite packages using these commands:
$ sudo apt-get update $ sudo apt-get install ipython python-opencv python-scipy $ sudo apt-get install python-numpy python-setuptools python-pip $ sudo pip install svgwrite
Then install SimpleCV itself using the command:
$ sudo pip install https://github.com/sightmachine/SimpleCV/zipball/master
