> It's even simpler to make artificial neurons vote for a circle center. Is it? It's not conceptually simpler: people can more easily imagine circles around points converging to a center, so they can also put that idea into code more easily. > you can apply the method to other shapes as well. Yes you can. Read about Hough. I just presented the one that is the most enlightening. I may be biased against neural network approaches and their likes, because I see them as black boxes with failure modes that are hard to predict or work around: I prefer what I can understand and explain, and unfortunately, it seems at odd with the current demographics of ML (cf https://news.ycombinator.com/item?id=27361812 https://news.ycombinator.com/item?id=27361812 ) who has no clue about what makes these black boxes tick, sometimes even after they get a PhD in the dark art of tweaking black boxes.
