“OpencCV is a multi-platform library, but this article
will be focused only on OpenCV using Linux operating system (
although, just the installation of the OpenCV library and video
camera is platform-specific, all examples in this article should
compile on any platform where OpenCV is properly installed such as
Mac OS, MS Windows and etc.). Reader will be guided through a
step-by-step guide on how to install and use some of the basic
functions of OpenCV library such as displaying images, playing a
video or using a video camera to process a video input
stream.”
