Computer vision is interesting. Despite computers being created by people, the way a computer sees versus the way a human sees is different. I’m especially interesting in how computer vision isn’t ‘general’ like human vision is, i.e, computers do not have a set function for its visual inputs. Computer vision relies on assumptions, and it uses those assumptions to analyze the world. If the assumptions are not met, then the computer cannot see. Humans do not have the problem of relying on assumptions of the real world, we see what we see. Any assumption of what we might see does not change what our vision can perceive.
Some of the assumptions we can place on the computer are ways to emphasize the contrasts of people. Basically, explain to the computer what makes humans different from each other, and what makes objects different from humans. Maybe an assumption you must set for a computer is that humans have heat to them, which makes it so that the computer can ‘see’ humans because it can see the heat they exude.
I think the limitations set on computer vision has actually cause people to be a lot more creative in interactive arts. If a computer needs certain arguments to see, then you can hide things from the computer, and you can make the computer only see what you want it to. A really silly example is maybe making the computer only ‘see’ if a human raises their arms in the air, which means that the human can ‘hide’ themselves from the computer. Having the human be an active participant in what the computer can see makes the artwork creative in a way we probably would not have considered if computers just had normal human vision.
