Morphological images

What it does

Here's a cool little topic. Let's think about how to extract borders in an image. I'm sure you could think of hundreds of heuristics, but I'd like to discuss one particular heuristic that, indirectly, leads to some pretty cool results relating to cellular automata. The technique is called "morphology", and it's one of those ideas which starts out with very simple rules, but, when the rules are composed, can yield complex behaviour. The central components in morphology are that of a union , complement and erosion of images. We'll only be working with pure black-and-white images here, but this can all be extended (with some effort) to grayscale and color images. If we represent images $A$ and…from danielrapp.github.io
