Before Object Oriented Programming (commonly referred as OOP), programs were written in procedural language, they were nothing but a long list of instructions. On the other hand, the OOP is all about creating objects that can interact with each other, this makes it easier to develop programs in OOP as we can understand the relationship between them.

Wait until all files get extracted. It will create a new directory  C:\opencv  which contains OpenCV header files, libraries, code samples, etc. Now you need to add the directory  C:\opencv\build\x86\vc10\bin  to your system PATH. This directory contains OpenCV DLLs required for running your code. Open  Control Panel  →  System  →  Advanced system settings  →  Advanced  Tab →  Environment variables... On the System Variables section, select  Path  (1),  Edit  (2), and type  C:\opencv\build\x86\vc10\bin;  (3), then click  Ok . On some computers, you may need to restart your computer for the system to recognize the environment path variables. This will completes the OpenCV 2.4.3 installation on y...
