Difference density map
Okay, kiddo, let's talk about density maps. Imagine you have a lot of things in a box - toys, books, snacks, and more. Some of these things take up a lot of space, like a big toy truck or a heavy book, and some things take up very little space, like a tiny snack or a small toy car.
Now, let's say you want to see which things are packed the tightest in your box. That's where a density map comes in. It's like a special map that shows how many things are in different parts of the box, but it also shows how tightly packed they are.
At its simplest, a density map can show you where the most toys are in your box. But a more advanced density map can show you which areas of the box have the most heavy books or the most small toys. By looking at the different colors on the map, you can see which parts of the box are really crammed full, and which parts have a bit more extra room.
Now, let's say you have lots of different boxes, each filled with lots of different things. You could make a density map for each box and compare them. Maybe you'll notice that the boxes full of snacks and small toys are always less densely packed than the boxes with bigger, heavier things inside. That's because the lighter things don't take up as much space, so they don't need to be packed in as tightly.
So, that's what a density map is - a special kind of map that shows you how tightly things are packed in a certain area. It's like a way to see which parts of a box (or any other space) are really full, and which parts have a little more breathing room.
