Algorithm to differentiate parts that are separated?

Question

Let's say I have an image with some shapes on it. Is there any algorithm that knows that there are multiple shapes on it, based on if they are separated or not?

Answer 1

I used an algorithm called "connected component labeling". I used these intructions for the implementation: https://towardsdatascience.com/implementing-a-connected-component-labeling-algorithm-from-scratch-94e1636554f
