What are mosaic algorithms?

A mosaic algorithm is like a puzzle that helps computers put together small pieces to make something big and clear.

Imagine you're looking at a photo on your phone screen, but it's blurry, kind of like when you squint at a drawing from far away. Now picture the image as being made up of tiny colored squares, like a mosaic in a bathroom or kitchen. A mosaic algorithm helps the computer figure out what color each little square should be so that, when they're all put together, the whole picture becomes clear again.

Think about your favorite puzzle. Each piece is small and has a certain shape and color. The mosaic algorithm works like you putting those pieces in place, it looks at the blurry parts of an image and guesses what each tiny square should look like to make the full, clear picture.

Sometimes, instead of using just one guess, the computer tries different ones, kind of like when you're not sure if a puzzle piece fits, so you try it out in a few places until it clicks. This way, the whole image gets clearer and more colorful!
