OpenCV, a cross-platform computer vision library based on BSD licensing (open source), can run on Linux, Windows, Android, and Mac OS operating systems. It is lightweight and efficient-consisting of a series of C functions and a small number of C + + classes, and provides interfaces for languages such as Python, Ruby, and Matlab, and implements many common algorithms for image processing and computer vision. OpenCV in C + + language, its main interface is also C + + language, but still retains a
