Computer vision is the branch of AI that gives computers the ability to make sense of visual information — photos, video and live camera feeds. It is what lets a phone recognize faces, a car spot pedestrians, and an app tell a cat from a dog or read text in a picture.
Like modern language AI, computer vision leans heavily on deep learning: models learn from large sets of labelled images what different objects look like. It powers everyday features such as photo search, document scanning and background removal. It also raises real questions around privacy and accuracy that are worth keeping in mind as it spreads.
