Software To Authenticate Paintings

eldavojohn writes, "There's a new software tool out and about called Authentic which analyzes paintings to determine if they are indeed authentic works of the artist. If you don't think this is a serious problem to tackle, some experts estimate up to 15 percent of 'original prints' sold at auction houses are actually fake. From the article: 'By dividing 145 digitized paintings into pixels and analyzing the colors of each and how they compared with nearby pixels, the system was able to spot patterns unique to the painter. The software also showed Van Gogh's use of complementary colors (PDF) increased during his most active period from 1885 to 1890, according to the study published in Pattern Recognition Letters... In tests, Authentic performed as well as 15 human volunteers who were each given a small segment of a painting to study.' I've heard of many tools that analyze texts to verify the author but this is an extra dimension and a new frontier for pattern recognition. Tacking on another dimension, how much longer until we are able to analyze video in the same way?"

    What if I *still* don't think this is a serious problem?

    The value of those pictures is a pure bubble anyway, if you can willingly give a $10k or so for a mere painting and it looks real to you, maybe it doesn't matter if it's fake. Better not tell you otherwise.

    While not obvious at first site, there's a very tight relation to the "authenticity" of paintings (and antiquated things as a whole), and... digital piracy.

    In both cases we're talking about things that can't cover their announced value just for what they are. Instead you're told they own some sort of authenticity, and thus cost X dollars.

    In both cases you can make much cheaper copies (or free copies) so abuse will always happen, unless we wisen up and stop paying for "star power", and artificially limited supplies.

      A thing commands whatever price someone is willing to pay. If their willingness is based on a fraud (a fake painting, for example), then that blows the viability of that marketplace.

      Whether you, personally, can imagine paying a lot of money for, say, a canvas that Picasso personally touched and applied paint to - well, it just doesn't matter. Some people really, really, really would like to have (and show to people) something completely unique that Georgia O'Keeffe or Titian etc personally created, with their own hands. It's literally a piece of history. When someone passes off a fraud as a piece of history, that's... fraud.

  2. Think of the Alternative by eldavojohn · · Score: 2, Insightful
    So I need to license this fine piece of software to make sure my fakes are not fakes?
    I believe the alternative is for you is to pay an 'expert' to analyze your work and fill out a certificate of authenticity. I'm no expert but I believe this gets pretty expensive with many many works of art requiring many different expert's (for each artist's) time.

    Now, this software doesn't yet work for all artists but I would imagine that if I spent large amounts of money on art, I would prefer my auction house that I frequent to have this service ready so I can see for myself that the computer gives me a 95%+ level of confidence that it is indeed an original. That's not to say the certificate of authenticity isn't necessary, it'd just be nice to know before bidding and probably help the auction house catch frauds.

    While the initial acquisition of this software might be pricey, the long term value of ensuring works are originals is, well, probably worth a lot more.

  3. Doesn't really help stop forgery. by soricine · · Score: 2, Insightful

    This tool depends on having a collection of 'known good' works in order to make a comparison. But quite often a painter doesn't paint like 'himself'. False positives would be very easy. When van Meegeren forged his Vermeers in the thirties, the paintings didn't have all the signature marks of Vermeers. They were purported to have been from a hitherto little-known period of Vermeer's work.

  4. I've always wondered about that too. by NotQuiteReal · · Score: 3, Insightful
    I have alway wondered why there is such a premium on "an original". Especially art.

    Maybe it is just the bias of a geek, used to mass-produced goods. Take a nice CPU for example, A multi-million transistor technological work of art. First copy - billions, subsequent production run, pennies apiece - all the same.

    If you really like a painting, you can get a print. Want more? You can get reproductions, done brushstroke, by brushstroke. 99% of humanity couldn't tell the difference, your freinds might know you don't have the bucks for the original. In 200 years will an antique 20th century reproduction of a 19th century masterpiece be worth much less than the original?

    Many gemstones can be reproduced too. Synthetic rubies, emeralds, saphires (and probably others) are chemically identical - and PERFECT. Yet, "natural" objects of the same materials are more costly. Why? Because it takes a lot more work to get the "natural" version out of the ground. Cosmetically, I'd take a fake emerald over a cloudy natural one any day. Oooh shiney!

    A collector will pay a premium for a mis-struck coin. You will take your defective DVD back to Wal-Mart. Stamp collectors on the other hand, like nice, well centered examples... unless they are way off, then - tada! It's a rarity.

    If I were to make some "fake" gold coins, out of real gold, are they really fake? I suppose the US Mint breaks old molds, but what if they found an old, rare $20 gold piece die, and decided to whack a few out, just for old times sake - official US minted gold coins with the original dies... what happens to the value of the "rarity"? (Some lawyer would probably take the case :-)

    I just don't get artifical scarcity - "rare pokemon cards", "rare beenie babies". Crap, forget rare, I have a yard full of unique, one-of-a-kind "pet rocks"!

    And now, the million dollar winner - "rare bits", yesiree, here are some copyrighted bits, far more valuable than those pirate bits...

    I think I am rambling.

    [point zero - re: Chinese sweatshops. Each has to decide whether one man's sweatshop is another's step in incremental societal evolution or a stumbling block to "progress".]

    1. Re: original artwork. The point is moot. The originality is already recognized, to wit, it is a popular work. There is a desire to have [even] a reproduction. The whimsical quality of "artistic value" has already been realized, hence the demend, either by true appreciation, or simply by gross peer pressure to be "with it".

    2. Re: scarcity, artificial. The whole point of numbered editions is exactly what I am talking about - artificial scarcity. I like art (that I like). I have purchased signed art. I paid less because it was "unnumbered". I liked the work. I could give two shits what number it was. It is the EXACT SAME PIECE. It is pretty arbitrary what number the artist puts on it.

    There is no longer any reason for works of "art" to be "lost to the ravages of time", by my definition. If it is "good", there will be many copies, because it has the essence of what makes it "good". Some copies are sure to survive. Is a unique "artistic statement" lessened because it is not the original embodiment of the idea?
