Object detection is a computer vision technique that identifies and locates objects within images or videos. It uses algorithms to analyze visual data and classify objects, such as cars, people, or animals, while also providing their positions in the form of bounding boxes. This technology is widely used in various applications, including autonomous vehicles, surveillance systems, and image search engines. By enabling machines to understand and interpret visual information, object detection plays a crucial role in enhancing automation and improving user experiences across different fields.
