Normalization (image processing)

When we take a photograph, sometimes the lighting might make some parts of the picture look brighter or darker than they really are. This can make it hard for us to see important details in the picture. Normalization is like giving the picture a big hug and making sure that everything looks the way it should.

To do this, we first look at the picture and figure out how bright or dark it is in different areas. Then we adjust the brightness or darkness of each area to make them more similar to each other. This helps us see details that might have been hard to see before.

It's like when you're coloring a picture and some parts are too dark or too light, it's hard to see the whole picture. But once you color in everything nicely, the whole picture looks better and you can see it more clearly. That's what normalization does for images.
