Is This Rembrandt a Real One?

Roland Piquepaille writes "About a year ago, I told you about how computer scientists from Dartmouth college were investigating digital images. But they're also interested in old paintings authentication, as reports Wired Magazine in The Rembrandt Code. Mathematicians are using high-resolution digital cameras and computers to examine old paintings and evaluate their authenticity. Even the New York's Metropolitan Museum of Art is asking them to discover which of the 42 paintings it owns and that were once believed to be Rembrandts are really authentic. The Wired article is pretty entertaining, but this overview contains more details, pictures and references about this authentication process."
