Eigenmoments

Ok kiddo, have you ever seen a picture of your face or your friend's face? They have features like eyes, nose, mouth, and ears, right?

Well, imagine we take a bunch of pictures of faces and we want to figure out what makes each face unique. We can do this by looking at the shapes and positions of each feature on the face.

Eigenmoments are special math things that help us compare and analyze different shapes in pictures. Think of them like special codes that tell us how similar or different shapes are from each other.

For example, if we take a bunch of pictures of faces and compare the shapes of their noses using eigenmoments, we can find out if some noses are bigger or smaller than others, if they are curved or straight, or if they have a pointy or round tip.

Eigenmoments help us analyze and compare shapes in different pictures, which is really useful for things like facial recognition technology or image classification.

So remember, eigenmoments are like special codes that help us understand differences in shapes in pictures. Pretty cool, huh?
