A Different Form of Color Vision in Mantis Shrimp - 4 views

  •  
    Mantis shrimp seem to have 12 types of photo-receptive sensors - but this does not really improve their ability to discriminate between colors. Speculation is that they serve as a form of pre-processing for visual information: the brain does not need to decode full color information from just a few channels which would would allow for a smaller brain. I guess technologically the two extremes of light detection would be RGB cameras which are like our eyes and offer good spatial resolution, and spectrometers which have a large amount of color channels but at the cost of spatial resolution. It seems the mantis shrimp uses something that is somewhere between RGB cameras and spectrometers. Could there be a use for this in space?

    > RGB cameras which are like our eyes ...apart from the fact that the spectral response of the eyes is completely different from "RGB" cameras (http://en.wikipedia.org/wiki/File:Cones_SMJ2_E.svg) ... and that the eyes have 4 types of light-sensitive cells, not three (http://en.wikipedia.org/wiki/File:Cone-response.svg) ... and that, unlike cameras, human eye is precise only in a very narrow centre region (http://en.wikipedia.org/wiki/Fovea) ...hmm, apart from relying on tri-stimulus colour perception it seems human eyes are in fact completely different from "RGB cameras" :-) OK sorry for picking on this - that's just the colour science geek in me :-) Now seriously, on one hand the article abstract sounds very interesting, but on the other the statement "Why use 12 color channels when three or four are sufficient for fine color discrimination?" reveals so much ignorance to the very basics of colour science that I'm completely puzzled - in the end, it's a Science article so it should be reasonably scientifically sound, right? Pity I can't access full text... the interesting thing is that more channels mean more information and therefore should require *more* power to process - which is exactly opposite to their theory (as far as I can tell it from the abstract...). So the key is to understand *what* information about light these mantises are collecting and why - definitely it's not "colour" in the sense of human perceptual experience. But in any case - yes, spectrometry has its uses in space :-)

The Duel: Timo Boll vs. KUKA Robot - YouTube - 3 views

  • Man against machine.The unbelievably fast KUKA robot faces off against one of the best table tennis players of all time.
  • More: www.kuka-timoboll.com
  •  
    As people point out in the comments: a bit fake. But nevertheless a good production and a definitely cool advertisement for KUKA! I enjoyed it!
  •  
    yeah check out the making of, it's a nice movie and what would robotics movies be without movie magic :) somewhere they mentioned a vision system, which I think based on the making-of video they haven't really used for the video shoot

Silicon Valley celebrates Moore's Law 50 years anniversary - 2 views

  •  
    A bit late, but it is very interesting and instructive to listen to Gordon Moore's words "It almost doubled every year (...) so I said in the next 10 years it's going to continue to double every year, we are going to go from 16 components on a chip to 16 000. Pretty wild extrapolation!". This extrapolation (exponential with only 5 initial points) is now well-known and is one of the things that changed the World, it is pretty amazing how this "wild" futuristic vision came true.
  •  
    A great source is also the blog from Chris Mack (http://life.lithoguru.com/?p=451) who is a semicon pioneer and publisher of many books on the subject. He wrote an article for IEEE Spectrum on Moore's law and its future. Find it here, http://spectrum.ieee.org/semiconductors/processors/the-multiple-lives-of-moores-law

    Whenever I think about moore's law and extrapolating like that I end up back at this xkcd comic https://xkcd.com/605/

iRobot Brings Visual Mapping and Navigation to the Roomba 980 - 1 views

  •  
    Finally the thing will have a little more artificial intelligence than just "bump into wall, turn a bit, repeat". We've known for a while now that iRobot has been developing robots with wireless integration along with intelligent navigation capability based on VSLAM (Vision Simultaneous Localization and Mapping). We've know this for enough of a while that it's been a little bit frustrating to see iRobot's most recent Roomba upgrades come out without those neat features.

Spaceflight Now | Breaking News | ESA needs to 'tighten the belt' amid budget crisis - 2 views

  • ESA is freezing spending
  • France is planning to boost its funding by 12 percent
  • ESA selected Thales Alenia Space and OHB Technology to build the satellites, but the production contract is still bogged down by Germany's complaints about the distribution of MTG work between France and Germany
  •  
    no much news in regard to the january's talk of Dordain althought just a thought : what if ESA tries to make money - as CNES does - rather than just spending it ?
  • ...1 more comment...
  •  
    to begin with european industry (and probably governments) would complain that ESA was taking business away from industry? or any part that started to make money would be quickly spun-off
  •  
    really bad interview in my view ... btw: how is CNES making money and how much?
  •  
    CNES is known to be a semi-autonomous agency in the sense that it can auto-finance parts of its activities. Besides the money coming from the state, money comes from the participation of CNES in private companies (e.g. Arianespace) and its own activities (e.g. SPOT among others...). It is about 400M€ per year (almost a class-M mission in Cosmic Vision). For the figures (in French): http://www.cnes.fr/automne_modules_files/standard/public/p4354_c050f7963b54a839a843723401bfddf2budget.pdf

Neural Networks Designed to 'See' are Quite Good at 'Hearing' As Well - 2 views

  • Neural networks -- collections of artificial neurons or nodes set up to behave like the neurons in the brain -- can be trained to carry out a variety of tasks, often having something to do with pattern or sequence recognition. As such, they have shown great promise in image recognition systems. Now, research coming out of the University of Hong Kong has shown that neural networks can hear as well as see. A neural network there has learned the features of sound, classifying songs into specific genres with 87 percent accuracy.
  • Similar networks based on auditory cortexes have been rewired for vision, so it would appear these kinds of neural networks are quite flexible in their functions. As such, it seems they could potentially be applied to all sorts of perceptual tasks in artificial intelligence systems, the possibilities of which have only begun to be explored.

The 70 Online Databases that Define Our Planet - 0 views

  • an ambitious European plan to simulate the entire planet. The idea is to exploit the huge amounts of data generated by financial markets, health records, social media and climate monitoring to model the planet's climate, societies and economy. The vision is that a system like this can help to understand and predict crises before they occur so that governments can take appropriate measures in advance.

NASA budget for 2011 eliminates funds for manned lunar missions - washingtonpost.com - 3 views

  • NASA's grand plan to return to the moon, built on President George W. Bush's vision of an ambitious new chapter in space exploration, is about to vanish with hardly a whimper
  • a commercial spacecraft that could taxi astronauts into low Earth orbit
  • Obama budget as disastrous for human space fligh

    Personally I think this is great.

  •  
    what is great exactly ? No human beings will put a foot on the Moon, or Mars, in the next 22 yrs and more ... what an awful waste!
  •  
    Well, the constellation program was a waste of money in its current form, overrun by delays and insufficient budget. We would have had Apollo 2.0 sixty years later, for what? At least now they are talking about going to asteroids, martian moons and stuff like that.
  •  
    I agree that Constellation was a mistake. It is though a pity that now human Mars missions would certainly happen even later than initially hoped.
