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)
