Algorithms To Reassemble Ancient Map of Rome

Posted by timothy on from the check-under-the-couch dept.

MattJ writes "The BBC reports on a Stanford project to reconstruct pieces of an ancient, detailed, 60' by 43' 'map of Rome carved into stone slabs about AD 210 but later broken into fragments.' ... So complicated is the jumble of parts that for decades the map pieces have been referred to as 'the biggest jigsaw in the world.' Researchers developed algorithms to assemble the 3D fragments of the map, and have had some success."

    Perhaps I'm beeing to pessimistic, but I don't think they'll get to far with this project, unfortunately. There is, after all, only about 15% of the map which has been found, in no less than 1,186 pieces. Many of them probably very similar. As the article says, the program "has found seven high-probability matches and a host of other possibilities".

    But the idea is very cool. Probably this could make it easier to put together pieces of other artifats like clay tablets and the likes, and speed up the field of archaeology, which has in some cases been painfully slow.

    Cuneiform recognition software, anyone?

      I wonder if the algorhythms used in the distributed computing effort to find cancer cures could be adapted toward this - it would seem like you could get a lot of Italians to dedicate some cysles to the project.

      I agree tho, that archeologists and paleontolgists will likely be the first to really benefit from the software they are currently using - piecing together skull fragments or amphorae would seem to be pretty analogous tasks.

    Inventing...

    In my high school biology class, my teacher made an incredibly insightful comment that I've found applies to many fields of problem solving:
    "If it's going to take 10 years to solve the problem using current technology, then spend 3 years working on making new technology, then 3 years using the new tech. Now you've done it it 6 years instead of 10, just by 'procrastinating' and working on your tools first!"

    From the BBC article, we see Professor Marc Levoy's quote in highlight, "In doing so, we have created the largest and most detailed model of a cultural artefact"

    Think about this for a sec... they've invented tech that provides a better model for cultural artifacts than we've ever had before. Sounds like a key boost in the right direction for this field of engineering.

  4. Very similar to a 1970 reconstruction by Flexagon · · Score: 4, Interesting

    Nice to see this technique advance.

    I have a November 1970 issue of National Geographic with an article entitled "Computer Helps Scholars Re-create an Egyptian Temple" by Ray Winfield Smith that describes something very similar. A summary is embedded here.

    The article says that they had to deal with as many as 30,000 pieces, many of which had disappeared over time. They shot B&W pictures of the pieces at the rate of 400/day, and then created punched cards (and then tape image) for each picture. Each card had the piece number and codes for various attributes (such as paint color, figures, hieroglyphs) of the piece. They could then search for other pieces that matched attributes of a subject piece. IBM supplied them access to a computer.

    BTW, the issue's headline article was "Behold the Computer Revolution", a nice historical piece now.
