I extracted files from OpenCV.2.4.6.0.exe. What next?
Perhaps I was supposed to start by reading Open Tutorial CV++, and download/install Visual Studio Express 2012 too? Apparently I will need to register by giving your email address to obtain the free product key. That plus setting up an environmental variable, plus do other things. Apparently, Studio Express is an IDE. That appears to complete the build. Following sections (Basics of Open OpenCV API, ...), are examples on how to write code.
Generally, I plan to use OpenCV for image processing. I plan to use C++. I think I saw tutorials on various languages.
Comments?
