    Task                                                               Information Literacy

                        Let’s say you’re using your smartphone, which uses face recognition to unlock the screen. The
                        phone’s camera captures your face, and the computer vision system compares it with stored
                        images of your face in the phone’s memory.

                        One day, a friend tries to unlock your phone using their face. The AI system recognises that
                        the face does not match the stored one and refuses to unlock, ensuring your privacy.
                        Now, answer the following question:

                        What part of the computer vision system allows the smartphone to recognise and match your
                        face? How does the system work to make sure it only recognises the right person?

                             Let’s CatCh uP

                       Name any two uses of computer vision in real life.

                            NATURAL LANGUAGE PROCESSING (NLP)

                     Natural Language Processing, or NLP, is the domain of AI that enables communication between
                     humans and machines. It understands and works with human languages, such as English, Hindi,
                     and French, and can read, write, translate, and respond like a person. In short, we can say that
                     Natural Language Processing teaches computers to talk and understand human languages just

                     as we do.

                                                                                                 Exploring AI Domains  93
