Instagram. These filters use computer vision to identify
facial features and apply virtual elements like animal
faces, makeup or virtual effects in real-time, enhancing
user interaction with digital content.

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?

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.
