For decades archaeologists in Greece have been trying to reconstruct wall paintings from Thera -- now known as Santorini-- an island civilization that was buried under volcanic ash more than 3,500 years ago.
The Herculean task -- more than a century of further work at the current rate -- soon may get much easier, thanks to an automated system that works like a ''virtual archaeologist.''
Developed by a research team from Princeton University, in the US, the technology has been presented this week at the Association of Computing Machinery's annual SIGGRAPH conference in Los Angeles.
While other computer systems rely on expensive equipment that had to be operated by computer experts, the new technology uses inexpensive, off-the-shelf hardware and is designed to be operated by archaeologists and conservators rather than computer scientists.
The system employs a combination of powerful computer algorithms and a processing system that mirrors the procedures traditionally followed by archaeologists.
"We mimic the archaeologists' methods as much as possible, so that they can really use our system as a tool," said Szymon Rusinkiewicz, an associate professor of computer science whose research team led the Princeton effort.
The system is still being perfected, but it already has yielded promising results on real-world examples: when tested on some fragments from a large wall painting, it found 10 out of 12 known matches, and two more previously unknown.
"When fully developed, this system could reduce the time needed to reconstruct a wall from years to months. It could free up archaeologists for other valuable tasks such as restoration and ethnographic study," Rusinkiewicz said.
