For those developing on Debian based Linux, these are the steps:
1. Install python-opencv package with apt-get/aptitude
2. You can get the Haar cascades here - http://alereimondo.no-ip.org/OpenCV/34
3. Run the same code, just make sure to use one of the cascades downloaded from step 2
Line 60:
parser.add_option("-c", "--cascade", action="store", dest="cascade", type="str", help="Haar cascade file, default %default", default = "/usr/local/Cellar/opencv/2.2/share/opencv/haarcascades/haarcascade_frontalface_default.xml")
Change default to the haar cascade file path, or use --cascade option to specify it.
4. Execute
Edit: For non-Deb based distros, use your package manager to download/install opencv for python (or compile it) and continue from step 2.
