OpenCV is an open-source library used in Python for computer vision and image processing tasks. It provides tools for reading, processing, and analyzing visual data, such as images and videos. Common applications include face detection, object recognition, and motion tracking. For example, you can use OpenCV's cv2.CascadeClassifier to detect faces or the cv2.Canny() function for edge detection. OpenCV also supports advanced functionalities like image segmentation, feature extraction, and real-time video processing, making it widely used in domains such as robotics, healthcare, and augmented reality.
