Pinpointing Human Activity in a Video Barrage

24.01.2003


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-Arie’s 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.


"Security guards have to monitor 10 or 20 screens continuously, and it’s very boring," said Ben-Arie, a professor of electrical and computer engineering. "A machine won’t get bored. It’s much more practical to have the computer do it."

Ben-Arie’s method, for which he has a provisional patent, identifies and tracks nine major body parts and needs only a few poses from a video segment to distinguish an activity. Yet the method is robust enough to differentiate between activities as similar as walking and running, even with several people in the video.

The technique may have medical applications in physical therapy or analysis of motor function. Other applications might include choreography or sports training, in which a dancer’s or athlete’s movements can be compared against ideal or standardized movements. Ben-Arie and his students described the method recently in IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI)

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
