URI researcher develops advanced

27.01.2004


Since most criminals only strike when they aren’t being watched, reliable surveillance of homes and businesses is a round-the-clock job. A University of Rhode Island researcher has made that job considerably easier and less expensive, thanks to a new technology he developed that can automatically track moving objects in real time.



Using low-cost, commercially available hardware, the Automatic Image Motion Seeking (AIMS) camera follows a moving object and keeps the target at the center of the field of view.

"This camera has broad impact for security surveillance, because it eliminates the need to have a full-time guard watching a video screen," said Ying Sun, URI professor of electrical engineering who began developing the device in 2002. "It’s one intelligence level above any other existing system, and we’ve found the right compromise between speed and accuracy."


It’s also inexpensive. Sun, a Wakefield resident, said that the system can operate on a $30 webcam as well as on more sophisticated equipment. It just requires a motor-driven, pan-tilt camera mount and a processor. Using low-cost equipment, the system could cost less than $300, making it ideal for many home uses. And because it can track movements, one AIMS camera can be just as effective as several stationary cameras.

At a rate of 15 frames per second, the camera analyzes images for any motion. Once a moving object is found, it feeds that information to the camera mount to begin tracking the object as it moves.

"We’re working on adding ‘behavior modifiers’ to the system as well, so that once the camera identifies motion it can be programmed to continue to track a given size, shape or color regardless of any other motion," Sun said.
He also believes that a camera that can quickly track motion has a psychological effect on criminals. "If they see that the camera is following their movements, they may think that a security guard is manually operating the camera and is aware of their presence. It’s likely that the criminal would then decide to go elsewhere."

In addition to property surveillance at such places as ATM machines, businesses, warehouses, factories, and homes, the camera has applications for homeland defense, military uses, child monitoring, playground surveillance, border patrol, and video conferencing, among others.

"Existing video conferencing equipment requires the speaker to remain in one place in front of a stationary camera. With the AIMS camera people can walk around and the camera will automatically follow them," Sun said.

The technology is based on an image-processing algorithm for real-time tracking. Because of the effectiveness and computational efficiency of the algorithm, the feedback control loop can quickly achieve reliable tracking performance. The algorithm is implemented in the Visual C++ language for the Windows Operating System on a PC, however it could be configured to operate on an embedded PC, handheld computer or digital signal processor chip. Video recording can be triggered by the presence of motions and stored on a computer hard disk as AVI files. Motions can also trigger an alarm or other security measures.

Former URI graduate students Xu Han and Yu Guo worked with Sun on the project. All three are co-inventors of the AIMS tracking algorithm, which has a U.S. and international patent pending.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
