Gaussian filter

A Gaussian filter is a special tool that helps make things blurry in a certain way. Imagine you have a picture that looks a little bit too sharp, like you can see all the little details too easily. If you use a Gaussian filter, it will help make everything look a little more smooth and soft.

A Gaussian filter works by putting a little bit of fuzziness around each point in the picture. The fuzziness is like a tiny cloud that spreads out from each point. When all these little clouds combine together, they help make the picture look more smooth and blurry.

The name "Gaussian" comes from a man named Carl Friedrich Gauss who was really good at math. He figured out a special type of equation that describes how the fuzziness should be spread out. This equation is now used in the Gaussian filter to help make pictures look better.

So, to summarize, a Gaussian filter makes pictures look less sharp and more smooth by putting little clouds around each point in the picture using an equation invented by Carl Friedrich Gauss.
