YOLO

Definition

YOLO stands for 'You Only Look Once,' which is a real-time object detection system used in autonomous vehicles. It is designed to detect objects in images quickly and accurately, making it an essential component of perception algorithms in self-driving cars. This method processes the entire image at once, allowing for faster and more efficient detection, crucial for the safe navigation and operation of autonomous vehicles.
