What is computer vision and how is it used in AI?

Computer vision is an interdisciplinary field of study that deals with how computers can be made to interpret and understand visual information from the world around them. It involves teaching computers to extract information from images and videos, and to use that information to make decisions or take actions.

Computer vision is used in many applications of AI, such as self-driving cars, facial recognition systems, and medical image analysis. It can also be used for more basic tasks, such as image and video search, object detection and tracking, and augmented reality.

Computer vision is based on machine learning algorithms, which allow computers to learn from examples, rather than being explicitly programmed. These algorithms use statistical models to identify patterns and features in visual data, which can then be used to classify objects, detect anomalies, or make predictions.
