HOW TO INSTALL openCV in Win7 -64-bit

Question

I am facing problem in installing openCV in Win7 -64bit, and i need to know how to do it?

i have downloaded http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/ 131mb file from here and it doesnt contain any exe file, it contains some cmake file.

Help me. Thanks, sumit

Assuming you are using Visual Studio, after extracting the files to a location like c:\OpenCV-2.3.1\ you should setup a new project and link OpenCV libraries.

A couple of months ago I wrote a detailed tutorial explaining how to setup projects using Visual Studio 2010 in a 64bit machine. You can find the tutorial here.

I am surprised that you are not having trouble with your entire windows breaking down/slowing down. Please read this http://answers.opencv.org/question/3996/cannot-do-anything-with-opencv-anymore-on-windows/

If you are NOT having the same problem, I would love to hear how you managed to setup OpenCV to work with Visual Studio 2010 (or Visual C++ 2010 Express) on Windows 7 64-bit machine.

Once again, sorry that I technically unable to post it as a comment because I know that it is not ACTUALLY an answer.

I am not sure what are your situation about, I can download a .exe from that page directly. The whole 131mb file is an exe file.

You may try this direct link.

I've written a blog post which can help you with the installation. It includes detailed steps, right from adding the dll's to the PATH variable, to running a simple program. Hope it helps!
