I have posted a very simple method to install OpenCV 2.4 for Python in Windows here : Install OpenCV in Windows for Python

It is just as simple as copy and paste. Hope it will be useful for future viewers.

Download Python, Numpy, OpenCV from their official sites.
Extract OpenCV (will be extracted to a folder opencv)
Copy ..\opencv\build\python\x86\2.7\cv2.pyd
Paste it in C:\Python27\Lib\site-packages
Open Python IDLE or terminal, and type
```
>>> import cv2
```

If no errors shown, it is OK.

UPDATE (Thanks to dana for this info):

If you are using the VideoCapture feature, you must copy opencv_ffmpeg.dll into your path as well. See: https://stackoverflow.com/a/11703998/1134940

One thing that needs to be mentioned  You have to use the x86 version of Python 2 7  OpenCV doesn t support Python x64  I banged my head on this for a bit until I figured that out   That said  follow the steps in Abid Rahman K s answer  And as Antimony said  you ll need to do a  from cv2 import cv

As of OpenCV 2 2 0  the package name for the Python bindings is  cv  The old bindings named  opencv  are not maintained any longer  You might have to adjust your code  See http   opencv willowgarage com wiki PythonInterface   The official OpenCV installer does not install the Python bindings into your Python directory  There should be a Python2 7 directory inside your OpenCV 2 2 0 installation directory  Copy the whole Lib folder from OpenCV Python2 7  to C  Python27  and make sure your OpenCV bin directory is in the Windows DLL search path   Alternatively use the opencv-python installers at http   www lfd uci edu  gohlke pythonlibs  opencv

I have posted an entry to setup OpenCV for Python in Windows  http   luugiathuy com 2011 02 setup-opencv-for-python   Hope it helps

Actually you can use x64 and Python 2 7  This is just not delivered in the standard OpenCV installer  If you build the libraries from the source  http   docs opencv org trunk doc tutorials introduction windows install windows install html  or you use the opencv-python from cgohlke s comment  it works just fine
