Video cameras are used to keep an eye on many indoor and outdoor locations, but to pinpoint suspicious activity, human security guards or intelligence analysts have the unenviable task of watching dozens of video monitors or many hours of recorded video.
Supported by an NSF award, Jezekiel Ben-Arie and his students at the University of Illinois at Chicago have developed a technique, much faster and more reliable than previous methods, that allows a computer to recognize a human action contained in a video.
Ben-Arie envisions a system that will allow human analysts to search vast databases of digital video by animating the desired action with virtual "puppets" or by videotaping a person making the movements. Ben-Aries method makes it feasible to quickly find matching human motions within large amounts of video. This includes searches through databases of surveillance videos for suspicious activities, such as a person putting down an object and leaving.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
