During her doctoral research in the Netherlands, Gemma Piella developed a new method for processing images. With this method more details are visible at a lower resolution than the original image: both the wood and the individual trees are distinct. Piella also combined various images of the same object to produce a detailed complete picture.

Mathematician Gemma Piella has developed a new technique for processing images. For this she used a mathematical operation that makes use of so-called

American Heart Association meeting report

A small device can give doctors the “big picture” of patients’ vital signs, researchers reported today during the Resuscitation Science Symposium at the American Heart Association’s Scientific Sessions 2003.

The device, called “Vital Dust,” transmits patient data to a hospital or centralized location, allowing others to see the data and also gain a global view of all patients in the field who are being similarly monitored. I

STEELBIZ is an on-line information system designed to improve the performance of the European steel construction industry. It provides engineers with technical information, design guides, building regulations, case studies and, for broadband users, voiceover Continuing Professional Development (CPD) lectures.

The STEELBIZ project is led by the UK-based Steel Construction Institute (SCI) which represents some 600 SME members in 30 countries. In the last 15 years it has produced nearly 200 pub

Columbia researchers develop “fingerprinting” techniques for SAR mapping

Research by scientists at the Lamont-Doherty Earth Observatory at Columbia University shows that Synthetic Aperture Radar (SAR) polarimetry is a more superior technology for rapidly identifying disaster zones than the currently used optical remote sensing technologies, such as Landsat and SPOT. Their findings are published in the Journal of Geophysical Research, and coincide with an opportunity to outfit satelli

Findings could have implications for speech recognition, machine learning, information retrieval

Scientists at the University of California, San Diego (UCSD) have developed new insight into a formula that helped British cryptanalysts crack the German Enigma code in World War II. Writing in the Oct. 17 edition of the journal Science, UCSD Jacobs School of Engineering professor Alon Orlitsky and graduate students Narayana P. Santhanam and Junan Zhang shed light on a lingering mathematic

The digital world surrounding us is full of images. Many of them are very large and do not easily fit into small devices, such as smart mobile phones. Alexander Kolesnikov’s thesis brings a revolutionary change to this. He has invented the most efficient vector graphics compression technique in the world that will make all maps, drawings and cartoons fit into small but smart mobile phones.

Digital images on digital TV’s, DVDs and computer and mobile device displays come in two variants: ras
