First of all, let’s see how human vision works. How do humans see? Our process of seeing things is primarily
because of the presence of light. Humans see an object when the light bounces off an object and enters the
eyes through the cornea. Then through the nerves it enters the retina which is involved in color vision. Once an
object is seen by the eyes it needs to be understood by the brain. The next step is to understand what the image
is, and that is done by our brain. Our brain then identifies and understands other information like color, shape,
movement and other details about the image.

Brainy Fact
Two Swedish scientists, Hubel and Wiesel, experimented on Computer Vision using a cat as an input object.
This was the beginning of understanding the interconnection between computer vision and the human brain.
Tasks in Computer Vision Applications
Now we will study how Computer Vision works in the real world. The Computer Vision applications are based
on a certain number of tasks performed on an input image to get the desired output which can be used to do
predictions or analysis of data.
Let us discuss the tasks on the bases of which Computer Vision applications are based on.
