Computer vision.

Computer vision is the ability of a computer to recognize and interpret the content of an image. Put more simply, computer vision refers to a computer's ability to "see" the way humans do. Much like human sight, computer vision is a process through which visual sensation is transformed into visual perception. During this process, a computer receives visual data, analyzes it, and makes some decision about that data. While most of the visual data involved in computer vision is received through normal pictures or videos, it can also come from infrared sensors, ultrasonic sensors, or other sources. Computer vision helps a wide variety of computer-controlled machines to work more efficiently and more intelligently. For this reason, computer vision is a key component of many cutting-edge technologies, including self-driving cars, remote control drones, and robots. Moreover, as computer vision technology continues to evolve, the practical role it plays in modern life is likely to grow along with it.
