Human vision inspired supercomputer may drive cars someday

Washington, Sep 16 (ANI): Inspired by our remarkable ability to quickly navigate through the street recognizing cars, other people, trees and lampposts instantaneously, researchers at Yale have developed a supercomputer based on the human visual system that could one day operate cars on its own.

Dubbed NeuFlow, the system, developed by Eugenio Culurciello of Yale's School of Engineering and Applied Science, takes its inspiration from the mammalian visual system, mimicking its neural network to quickly interpret the world around it.

The system uses complex vision algorithms developed by Yann LeCun at New York University to run large neural networks for synthetic vision applications. One idea-the one Culurciello and LeCun are focusing on, is a system that would allow cars to drive themselves.

In order to be able to recognize the various objects encountered on the road-such as other cars, people, stoplights, sidewalks, not to mention the road itself-NeuFlow processes tens of megapixel images in real time.

The system is also extremely efficient, simultaneously running more than 100 billion operations per second using only a few watts (that's less than the power a cell phone uses) to accomplish what it takes bench-top computers with multiple graphic processors more than 300 watts to achieve.

"One of our first prototypes of this system is already capable of outperforming graphic processors on vision tasks," said Culurciello.

Culurciello embedded the supercomputer on a single chip, making the system much smaller, yet more powerful and efficient, than full-scale computers.

"The complete system is going to be no bigger than a wallet, so it could easily be embedded in cars and other places," said Culurciello.

Beyond the autonomous car navigation, the system could be used to improve robot navigation into dangerous or difficult-to-reach locations, to provide 360-degree synthetic vision for soldiers in combat situations, or in assisted living situations where it could be used to monitor motion and call for help should an elderly person fall, for example.

The study was presented at the High Performance Embedded Computing (HPEC) workshop in Boston, Mass. (ANI)
