New Photo Fraud Detection Software

Posted by ScuttleMonkey on Saturday February 4, 2006 @09:22PM from the get-the-red-out dept.

An anonymous reader writes "CNet is reporting that Hany Farid, Professor of Computer Science and applied mathematics at Darthmouth College, has developed a new version of his Image Science Group's photo fraud software now in use by the FBI and large media organizations. The current software is written in Matlab, but the new version will be written in Java making it much more readily available to local police and smaller media organizations. From the article: 'I hope to have a beta out in the next six months,' Farid said. 'Right now, you need someone who is reasonably well-trained to use it.'"

I saw a 60x slowdown in a journal paper describing this exact topic(Java vs. Fortran). Their summary was that it may be possible to get Java fast but by default Java is(was) slow.

Look at "Java for Numerically Intensive Computing: from Flops to Gigaflops" or "Java for high-performance numerical computing". These both tell that better libraries(for multidimensional arrays) and relaxation of the floating point requirements of Java can speed up things a lot.
