Human eyes don't work anything like cameras. The eye processes information that isn't just intensities of photons and their wave lengths—which is the only information collected by cameras. See Walter Pitt's "What the Frog Eyes Tell the Frog Brain" for an introduction: 'Fundamentally it shows that the eye speaks to the brain in a language already highly organized and interpreted, instead of transmitting some more or less accurate copy of the distribution of light on the receptors.'

- pdxww 8y agoA simple abstraction here: we put two high-quality monitors before our eyes and get all the data from them. Can we continue driving this way? Absolutely. This means that no matter how our eyes actually work, an array of RGB pixels is enough. I'd go further and say that a 64 x 64 grayscale camera at 10 fps is enough to drive a car. The real magic happens in the brain that reconstructs the 3D model and predicts what happens next.

If you had vision that bad, the State of California would not let you get a drivers license, they require at least one of your eyes to be 20/40. Anyway, the point of the GP is that the brain isn't the only piece of wetware doing image processing, but more to the point the current state of the art CV really is not up to the task. And it really doesn't seem like it's going to be there anytime soon.
- ethn 8y agoThat is an analogy not an abstraction but if you had read the paper or the single quote I provided, you would know that even relatively simple eyes (such as those of the frogs which cannot see still objects) don't only process a distribution of light intensity and frequency. The eye measures other information that is lost by the camera including photon phase, arrival time, polarization, orbital angular momentum, linear momentum, and probably many more measurements. More so, this is done by specialized organelles of the eye rather than by the brain.
