  1. Life is not a GretagMacbeth Colour Checker on New Sensor Has Real Per-Pixel RGB Sensitivity · · Score: 2

    If you design your system to make the GretagMacbeth checker to look good, it will most likely make reality look bad.

    Personally, I prefer reality ;)

  2. Wrong: 16 MP on New Sensor Has Real Per-Pixel RGB Sensitivity · · Score: 2

    The current leader is 16 megapixel made by Eastman Kodak, the sensor is 4080x4080 in a Bayer array, which means it has 16 million pixels. That creats an image that is 48 megabytes, or if you work in the raw mode 96 megabytes (since you need a 16bit dword to hold the 12 bit data).

  3. logs on New Sensor Has Real Per-Pixel RGB Sensitivity · · Score: 5, Informative

    There are a couple of problems with logarithmic sensitivities in electronics- the little potential wells fill up too quickly. Make them too deep and they lose the low level light, make them too shallow and the electrons spill out.

    Conventional AgX can capture around 14 stops of light (thats 2^14) - conventional paper can handle 8 stops or so... a typical scene has 2^11, give or take. Depends on the scene and the subject- obviously a shot of a barn with the door open in broad daylight is going to have a bit more range than a shot inside in a white room with light bouncing everywhere.

    So, what you really want, is to have the SOFTWARE be cognizant of higher bitdepth images. When you have 8 bits to capture a 10 bit scene, information is lost. So you throw some out... and you end up with muddled highlights and muddled shadows, and something in the middle that looks decent.

    Believe it or not, but alot of companies have spent alot of money trying to figure out the correct 'mental' representation of a greyscale- not even including colour. I'm partial to Kodak (I work there, but these views are mine).

    I've worked with extended bit depth images quite a bit and know that there is none (read, big fat ZERO) ms support for anything over 8 bits.... in fact, ImageViewer simply locks up and crashes. So any sort of solution that gives you extended tonal rendering are going to have to be custom solutions... and that probably won't sit well with the average person- "what do you mean i have to process my pictures before I can view them?!?!? I'll just go buy another camera" etc etc. Even if the benefits are enormous, there is the simplicity factor that drives it.

    I personally am interested in this sensor, but there seems to be the wrong website linked... which worries me...

  4. Unfortunately on Limited-Use DVD Technology · · Score: 2

    if Flexplay discs constituted 10% of all rentals, the technology would save 50 million gallons of gasoline, eliminate 111,000 metric tons of carbon emissions, 700 tons of hydrocarbons, and 1,000 tons of nitrogen oxides every year.

    Fortunately, the manufacture of the plastic disks will only require 400 million pounds of crude oil to be manufactured into disks, releasion only 700 tons of hydrocarbons, and just under a 1000 tons of Nitrogen Oxides each year.

    It would also eliminate 35% of the rental company businesses and employees, thus boosting the countries economy.

  5. 3ware is Painful! on The Amazing $5k Terabyte Array · · Score: 2

    Actually, I assembled a 600 gig storage device using the afore mentioned 3ware controller.

    First, there were hardware bugs and they recalled the controller

    Second, 3ware dropped the product line, but vendors were still telling me it was available.

    Third, they brought it back, and I had to get a drop ship

    I lost about 3 months on design phase due to this little tidbit.

    Now don't get me wrong, it's working now and seems reliable... but... there's always this nagging suspicion that something is going to go wrong and I'll lose all that data.

  6. PhotoCD/ FlashPix does that on New Sampling Techniques Make Up For Lost Data · · Score: 2

    Formats supported by Eastman Kodak Company-

    PhotoCD works with a differential 'error' image that was created by comparing the resampled to the original, and then that was compressed. Effect? Take a small image, blow it up by a factor of 2x, apply this itty bitty 'error' transform, and you have a nearly perfect 'fixed' image for the cost of some small change on disk space

    Then there is the 'much better clarity' etc statement- there's 'inverse point transform' for getting out defects.. they used that on the Hubble Telescope. Looked pretty good for being wildly out of focus.

    Everything you've mentioned is already available... the technique looks interesting but it's all data dependent ... given enough training data you can make a GA to give 'guesses' into any dataset.

    What's this have to do with SF? Even if there is a perfect, idiom-perfect translation, we Americans may simply not have the cultural background to understand it. Or even do it the justice it deserves.

    This is by no means a reason to stop trying- I frankly love SF and have a library rapidly approaching 1000 books... but until I bone up on my russian history, I am afraid these wonderful texts will fall short :(

    Of course, a 'monologue' like the put down at the bottom of those ancient texts you studied in Latin class (you DID read the Aeneid, didn't you?) was more than enough to get the underlying meaning, giving you the cultural explanations of the references provided. Maybe thats what their SF needs to be complete.

    Yes it's not a bank. Don't use it if you feel that way. There a reason you'd rather use PayPal instead of a credit card? What, cheaper? Well... Fraud's expensive- paypal has to cover their bases and if that means putting some people's cash in the icebox... that seems to be their choice.

    You want to make a difference, choose not to use them. Frankly the protections they have in place are, IMHO, a bit over kill but then again I've never had my money misappropriated by another individual.

    Obviously there will be complaints from legit users... but frankly it's got to work, else we'd see a few more of 'but all my cash was taken' etc etc.

    Just some thoughts- the business model is successful because they stay 1 step ahead, sometimes, of the people intending to exploit them. They don't hve the infrastructure as credit card companies- based entirely on the 'net.

    Basically, a strange object has started 'growing' on the backside of the moon, and when people are sent to investigate .... the team is killed. Immediately an elaborately orchestrated effort is made to 'retrieve' a sample of whatever is over there... and the idea of a 'clean' work area is presented.

    The fascinating aspect of the clean room is that it contains a series of self-interlocking mechanisms that, as a fail safe, can dump enough power into an XRay apparatus to sterilize everything with the building's sheilds. This is the ONLY allowed method of handling nanotech, and they claim it's extremely immature compared to what's going on on the moon

    Canon

    OK, there are the two manufacturers of high quality photo journalism cameras. GUess what- no 3 CCDs. Please research before you try to post that junk, yourself.

    Two- I say 12 bit. Thats because film holds 4 logE exposure information- in your terms that works out to be 12 bit, or 4095 levels of grey. That means it has to be stored in 16 bit, which means 2x as much information density as your standard 8 bit, 1 ccd camera.

    Three- No jpeg compression because, wow, jpg doesn't work very well with anything other than sRGB 8 bit images. Go figure! You want to talk about jpeg 2000, however, you can, but I'm afraid that there are no hardware solutions that do that currently and there are pitifully few software solutions. Heck the spec hasn't even been finalized.
    Four- no photoJournalist leaves his finger on the button for 36 frames- except maybe when the towers collapsed. You shoot in 3 to 5 shot bursts. Digital video is, wow, under 1 meg? Per frame? Captured at 1/125th of a second? Guess that wouldn't make a good large printed image, huh?

    Five- Ever drop a 1 gig microdrive from a height of 6 foot? Guess what- it doesn't survive the landing. Ever drop a roll of film and had your pictures scrambled? Didn't think so.

    I find you use arguments you've heard other people mention but have no insight into the technology, nor it's uses. Thanks for extrapolating Moore's law on storage devices- did you forget there is a quantumn limit to the size of information density on a magnetic platter? Guess what- you hit it. Might wanna look that one up yourself.

    Mainly for several points- one, backlash. What's going to happen when the server crashes and all your precious photos were on that HD?

    There is the instantaneous nature of the wire- this is where you get paid if your stuff hits it first. If it's second, you don't get the cash. *delete*. You can't do that with film- every image is preserved in perfect clarity... or not so perfect if you look at some of the photos from WWII of beach landings- all grainy, blurred, high contrast. The guy processing the film screwed it up. Still salvaged it tho...

    There is the whole aspect of quality (please don't rant to me about mp3s, OK? You don't know what you are talking about). For a typical digital camera, guaranteed, right off the bat, 67% of your image is fake. Yes, fake. Period. You can only capture 1 colour channel per pixel- the rest you have to make up. Look up Bayer Arrays if you don't believe me. Some 'faster' PJ (photo journalism) cameras use sensors with half as many pixels in the Y direction- that means that not only are 67% of the pixels fake, 25% never existed in the first place!

    So yeah, the pictures go on a file server for instant access- big deal. One Niminda worm and it's gone except for the backups. In 5 years who knows what the storage medium is gonna look like? (although I will argue CDs will probably always be around... they do degrade and who other than the photog (not the agency) is going to store all the images on CD?).

    I really worry about this... the information density of 35mm film is around 28 megapixel (thats 28x3 = 84 megs @ 12 bit = 168 megabytes per image) vs the high end digitals that are currently producing what, 6 meg files? Even the Kodak sensor is 16 megapixel-48 megs... but that does produce some STUNNING work. Of course it only captures at 0.5 fps for 5 frame burst... oh wait, my brand new SLR does 10 fps until I run out of film...

    Since you have an infinite number of selections to choose from, and as was demonstrated that base E is the most efficient to represent numbers in (ie, infinite representation in base e is better than other bases), then it stands to reason that quantumn computers based on light should be designed to utilize base e, but since that isn't very practical ternary might be the first logical step.

    And howcome I got rated offtopic? Quantumn computing is the logical next application of ternary computing, since binary is pretty much entrenched in everything from your local computre reseller to every time you toss a dime for 'heads or tails'.

    There's alot of room left to wiggle- you yourself have punched the numbers in and know what it takes. The first thing I thought of when I read the post is realtime face detection / catalog, database building, surveiliance for a small city / Olympic Games.

    With that much video feed coming in you either have to have 1000 dedicated operators or some sort of computer assisted recognition. Or come to face the tape at a later time.

    Very few cameras on the market will give you 30 fps non-interlaced. If you are willing to spend 5% of the budget of these 4K+ cameras... well, guess that gives an overall idea how much the budget is.

    Getting ideas on Slash dot is a great step, but it is in no way the a substitute for a thorough analysis of your bandwidth, backup, routing, and storage requirements. Period. Don't think you can administer this alone ;-) (don't get ruffled on that, I can't administer it alone either!:P)
