Welcome to the OpenCV 2.4.11 Windows Installation Guide !! If you are unsure where to start I would recommend starting at the beginning of Installation Cheat Sheet 1, then working your way through each of the 4 Cheat Sheets. It would be highly recommended to view the YouTube videos accompanying each Cheat Sheet (link available at the top of each Cheat Sheet). All installation/configuration procedures and programs have been thoroughly tested on Windows 7. To my knowledge they should all work on Windows 8/8.1, but this has not been tested by me personally so I cannot vouch for 8/8.1. Testing was performed on a Dell, HP, and Lenovo, all Windows 7 64-bit computers. Parts 1 - 4 cover the following: 1) Visual Studio 2013 and precompiled binaries 2) Python 2 3) Emgu CV (Visual Basic.NET and C#) 4) OpenCV compile from source, configuration with Visual Studio 2013 and Qt, and a Qt GUI program Enjoy !!
