OpenCV is an open-source computer vision library. OpenCV is an extremely optimized library with a focus on real-time applications.

OpenCV has 2500+ optimized algorithms, which includes a complete set of both classic and state-of-the-art computer vision and machine learning algorithms.

These algorithms can be used to detect and recognize faces, identify cars and license plates, identify objects, classify human actions in videos, track camera movements and track moving objects, etc.
