Wired: Software Detects the True Artist
Wired News: Software Detects the True Artist
Scholars have had their suspicions that the painting of Madonna and child credited to the Italian Renaissance master Pietro Perugino wasn't really done by him alone. But they could never be sure.
Now, a new set of software tools, developed by a Dartmouth College team, seems to confirm the art historians' doubts, showing evidence of at least four different painters working on the canvas. The programs' makers hope this will be the first in a long line of art authentication mysteries they can help put to rest, with code that can sort out real from fake.
"There are properties in an artist's pen and brush strokes that aren't visible to the human eye, but that are there nonetheless. And we can find them, through mathematical, statistical analysis," said Dartmouth computer science professor Hany Farid, who developed the algorithms, along with math professor Daniel Rockmore and graduate student Siwei Lyu.

Siwei Lyu, Dan Rockmore and Hany Farid: A Digital Technique for Art Authentication
Abstract:
We describe a computational technique for authenticating works of art, specifically, paintings and drawings, from high resolution digital scans of the original works. This approach builds a statistical model of an artist from the scans of a set of authenticated works, against which new works are then compared. The statistical model consists of first- and higher-order wavelet statistics. We show preliminary results from our analysis of thirteen drawings that have at various times been attributed to Pieter Bruegel the Elder, which confirm expert authentications. We also apply these techniques to the problem of determining the number of artists that may have contributed to a painting attributed to Perugino and again achieve an analysis agreeing with expert opinion.
För övrigt skulle jag gärna vilja se filmen The Math Life
