Introducing OpenCV

OpenCV is a C++ programming library, with real-time capabilities. As it is written in optimized C/C++, the library can profit from multi-core processing. A theoretical introduction about the OpenCV library is carried out in the next section.

In connection with the OpenCV library, here are some reasons for its popularity:

• Open source computer vision library
• OpenCV (BSD license—https://en.wikipedia.org/wiki/BSD_licenses) is free
• Specific library for image processing
• It has more than 2,500 optimized algorithms, including state-of-the-art computer vision algorithms
• Machine learning and deep learning support
• The library is optimized for performance
• There is a big community of developers using and supporting OpenCV
• It has C++, Python, Java, and MATLAB interfaces
• The library supports Windows, Linux, Android, and macOS
• Fast and regular updates (official releases now occur every six months)
