Human vision allows us to observe, recognise, and understand our surroundings through the
coordinated work of our eyes and brain. Computer Vision enables computers and machines to
perform similar tasks by analysing images and videos.

Let us understand in detail:

1. Awareness: Human eyes are natural and automatic. Humans are able to
identify familiar faces within seconds through perception and memory.

Computer Vision systems, on the other hand, must be trained with large
sets of data and algorithms in order to do the same thing.

For example, a human may easily identify a friend in a group of people, AI can only identify
faces after being trained on facial data.

2. Speed of understanding: Humans are able to fast process what they see
and frequently assign emotional significance to it. Computer Vision processes

images fast but does not understand emotions.
For example, a human can see a smiling face and interpret friendliness, whereas

AI can only identify the face as 'smiling' without understanding the context.
