OpenCV is an open source library for computer vision and image processing. It contains over 500 functions for tasks like facial recognition, object detection, motion analysis, and more. OpenCV supports Windows, Linux, and MacOS and can be used to build applications for tasks like human-computer interaction, robotics, and image segmentation in real-time. The library contains modules for core functions, GUI capabilities, camera calibration, and more. Common OpenCV operations include loading and displaying images, resizing windows, and basic matrix and image manipulations.
