I know that a lot of questions have been posted regarding the installation of OpenCV, but right now I need to install both OpenCV 2.4 along with OpenCV 3.0.0
Since there are a lot of research codes available online and the authors of these say that our code is not compatible with OpenCV 3.0.0, I am wondering how can I install both versions of OpenCV.
Even before the installation instructions, can somebody please tell me how to remove all the existing versions of OpenCV from my PC. I want to do a clean installation of OpenCV, with appropriate setting of all the environment variables.
Thanks in Advance.
