Oriented FAST and Rotated BRIEF (ORB)

Oriented FAST and Rotated BRIEF (ORB) is a computer vision technique used to detect and describe features in images. It identifies key points in an image, like corners or edges, and assigns a unique descriptor to each point based on its surrounding patterns. "Oriented" means it can recognize these features even if the image is rotated. This ability makes ORB efficient for tasks like object recognition and tracking in various applications, such as robotics and augmented reality, by allowing computers to understand and compare visual information robustly and quickly.
