Physics goes abstract

An image processing technique that is used to analyze galaxies might also have applications in the world of abstract art. Scientists in the US and Canada have shown that it might be possible to use "multi-fractal" analysis to distinguish between works by different artists (Phys. Rev. E72 046101). The works of the abstract expressionist painter Jackson Pollock have already been analyzed with fractal techniques by Richard Taylor of the University of Oregon and others.
