OpenCV under Windows

For those who are trying to run OpenCV under Windows you may have trouble installing things correctly.
The instructions on the OpenCV page are a bit out-of-date, this is our recommended installation procedure.

1. Install Python 2.7 from http://python.org/ftp/python/2.7.5/python-2.7.5.msi
2. Install the Numpy 1.10.2 superpack from https://sourceforge.net/projects/numpy/files/NumPy/1.10.2/numpy-1.10.2-w...
3. Download OpenCV 2.4.13 from https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.13/o...
4. Run the opencv-2.4.13.exe program to extract all the files
5. Find the extracted opencv\build\python\2.7\x86 folder
6. Copy the cv2.pyd file into C:\Python27\Lib\site-packages
7. Run Python from Start > All Programs > Python 2.7 > Python (command line)
8. The version shown should be 2.7.5
9. Run the following lines:
   

   import numpy
   print numpy.__version__
   import cv2
   print cv2.__version__
   

10. The versions show should be 1.10.2 and 2.4.13

This should be everything needed to simulate the image processing in the Race Code.
Note that the functions have changed in newer versions of OpenCV and therefore versions of 3.0.0 and later will need some minor changes to the code.
