  1. Re:extra-spectrum vision on Japanese Scientists Create Artificial Eyeballs · · Score: 1


    You can wire them up just as if they were more red cones; so a hot newspaper looks pink. However, at that rate, the person would have a lot of trouble making any sense of what he or she saw.


    But I think you could. They aren't impulse filters. If you wired up the near-IR sensors as red you would be able to distinguish "very red" IR from regular red. Frequencies that are red still have some green response, IR will have much
    less if any green response. You could plant

    nIR-R-O-G-Y-B-UV
    \ | /\|/\ | /
    R - G - B

    Something IR or Red has only a red response
    Orange has a Red & Green response, etc.

    You could also do this

    fIR-nIR-R-G-B-UV
    \ / \|/ \|/
    R - G - B

    This might make you red-green colorblind, but maybe just less sensitive to the transition.

    After a little combining in the eye you have basically the same inputs to the brain. I don't think this would be needed really, the brain learns to see, if it got a different set of initial inputs it would probably adjust. Just look at the color blind, most don't know they are until they take some test for it. I think the really hard stuff is making IR and UV receptors that work in a mammal.
    I agree that we know very little about how the brain actually processes vision. The parts we do know like the edge detecting filters don't need color.

  2. extra-spectrum vision on Japanese Scientists Create Artificial Eyeballs · · Score: 1

    Furthermore, the nervous system requirements to process the additional information simply are not there (infrared = red and your superspy can't see normal colors? Ooh, sign me up today.)

    I agree with you're other points, but not this one. I've read reports of some women having extra green receptors. They don't have extra resolution in their retina, just two sets of green receptors sensitive at different frequencies. This may explain why color blindness is less prevalent in women, if they start out with two and lose one they still can see color about as well as a man.

    If you managed to engineer new color receptors that weren't baked by UV and were sensitive from infrared to UV you could have the three RGB's and a UV and infrared. You would have a harder time finding the edge between a green and blue surface at the same brightness but it wouldn't be a handycap since we already have much lower color resolution than brightness res, just look at how JPEG and TV signals are encoded.

    I wouldn't be surprised if there is someone out there that can already see well in UV and infrared, there isn't much of an advantage so it won't wipe out our simple RGB eyes in the gene pool. I only discovered I was more sensitive to IR than average because I was getting blinded by the bright IR LEDs that others would only admit to seeing in a dark room. Not much of an advantage in our modern world, and with no extra 'regular red' sensitivity I couldn't really distinguish it from a bright red (it is really red, prolly cuz it's completely undetected by the blue & green receptors.)

    Still your other points hold, it's far off. If we can replace a blind newborn's eyes in 20 years with normal eyes that would be fantastic in and of itself.

    I'd really love to have 1024 individual sensors for a in-eye spectroscope though. "Johny is that a diamond or cubic zirconia on Sally's finger?" or better yet, "Cmdr. Checkov is that planet M-Class?"

Even if the programmer spent 2 weeks on 5 lines of code another pair of eyes often sees something that wasn't obvious to the first coder.

    Umm, no.

    I've been using this library the last couple years, and it reduces CPU demand. I was doing pupil tracking using it only for image capture, and I needed two PIII-860Mhz with 400Mhz RAMBUS memory. Using it for some of the basic image processing reduced demand so it almost ran on a single Athelon, I think the memory was too slow on those boxen, but I left the project at that point. Fast enough was 30 fps, and it was difficult even with the library. (We needed the 3D position of the eyes reliably at video rates for a stereo display and didn't want the user to have to wear anything.)

    They have pretty decent MMX algorithms which work out of the box. I'd have to say those that do write in C unless they absolutely can't avoid it. I was happy to squeeze an extra two cycles out of the inner loop of my MMX code, but I'd really rather have Intel do it since it's not the core of my work.

    Computers are slow and always will be, I'm a graphics person so 6 hours to render a frame is really slow, to real vision people processing an image for depth overnight is fast. We invent ways to use the CPU much well ahead of Moore's law. In another 50 years we'll be able to emulate dog vision! maybe... just run it overnight ;)
