ORB (Oriented FAST and Rotated BRIEF)

ORB, or Oriented FAST and Rotated BRIEF, is a computer vision algorithm used for detecting and describing features in images. It identifies key points, similar to human-like attention to important parts of a scene, and calculates their orientation for better accuracy. Then, it creates a unique descriptor for each point, making it easier to match features across different images. ORB is efficient and effective, allowing applications like image recognition, robotic navigation, and augmented reality to recognize objects and environments quickly, even in varying lighting or viewpoints. Its speed and robustness make it popular in real-time applications.
