15% Pre-order Discount - Age Factors in Biometric Processing
Due to publish in September 2013, Age Factors in Biometric Processing
discusses and analyses a wide variety of issues which describe the effects of human aging in the way biometric systems are designed and deployed. It has been compiled by an international panel of experts to explore the impact of the ageing process on biometric technologies and how such factors can be managed in practical situations.
This book provides an outstanding overview of biometrics-based identification solutions and has a widespread appeal for the rapidly expanding community of researchers across academia, industry and government.

Digital cameras, medical scanners, and other imaging technologies have advanced considerably during the past decade. Continuing this pace of innovation, an Austrian research team has developed an entirely new way of capturing images
based on a flat, flexible, transparent, and potentially disposable polymer sheet. The team describes their new device and its possible applications in a paper published today in the Optical Society’s (OSA) open-access journal Optics Express
Imagine a camera that allows you to see through a crowd to get a clear view of someone who would otherwise be obscured, a smartphone that matches big-budget lenses for image quality, or a photograph that lets you change your point of view after it's taken. The ideas may sound outlandish but they could become commonplace if "computational photography"
lives up to its promise. Unlike normal digital photography - which uses a sensor to capture a single two-dimensional image of a scene - the technique records a richer set of data to construct its pictures. Instead of trying to mimic the way a human eye works, it opens the activity up to new software-enhanced possibilities.
Using an innovative new camera on board a sounding rocket, an international team of scientists have captured the sharpest images yet
of the Sun's outer atmosphere. The team discovered fast-track 'highways' and intriguing 'sparkles' that may help answer a long-standing solar mystery. Prof. Robert Walsh of the University of Central Lancashire (UCLan) will present the new results on Monday 1 July at the RAS National Astronomy Meeting in St Andrews, Scotland.
A practical new approach to holographic video could also enable 2-D displays with higher resolution and lower power consumption. Today in the journal Nature
, researchers at MIT’s Media Lab report a new approach to generating holograms that could lead to color holographic-video displays
that are much cheaper to manufacture than today’s experimental, monochromatic displays. The same technique could also increase the resolution of conventional 2-D displays.
Laser technology reveals lost city around Angkor Wat - Researchers find vast cityscape hidden under deep vegetation linking the Cambodian temples complex. Airborne laser technology
has uncovered a network of roads and canals, illustrating the remains of a bustling ancient city linking Cambodia's famed Angkor Wat temples complex. The discovery was announced late on Monday in a peer-reviewed paper released early by the Proceedings of the National Academy of Sciences journal. The laser scanning revealed a previously undocumented formal urban planned landscape integrating the 1,200-year-old temples. The airborne lasers produced a detailed map of a vast cityscape, including highways and previously undiscovered temples, hidden beneath dense vegetation on top of Phnom Kulen mountain in Siem Reap province. It was the lost city of Mahendraparvata.
Many states are using the technology to scan driver’s licenses to prevent identity fraud. It led to the arrest of a suspected arsonist in New York. And while facial recognition technology
could not identify the Boston Marathon bombing suspects, police used the software in their search. These recent headlines illustrate the benefits this technology provides for law enforcement agencies in an investigation. Not surprisingly, many businesses also see an advantage in using facial recognition, not for crime-fighting, but to reach customers. However, Brian Mennecke, an associate professor of information systems at Iowa State University, questions whether customers are ready for it.
PITTSBURGH-Researchers previously have shown that a depth camera system, such as Kinect, can be combined with a projector to turn almost any surface into a touchscreen. But now researchers at Carnegie Mellon University have demonstrated how these touch-based interfaces can be created almost at will
, with the wave of a hand.
A transparent computer that allows users to 'reach inside' and 'touch' digital content
has been unveiled at the TED conference in LA. Jinha Lee has been working on the SpaceTop 3D desktop in collaboration with Microsoft.
A 3D printing technique that produces clusters of stem cells
could speed up progress towards creating artificial organs, Edinburgh scientists have claimed.
Cheap sensors that help cars avoid collisions could emerge from research into a lens-less imaging system
. US scientists have used metamaterials to build the imaging system, which samples infra-red and microwave light.
Rugby Football Union is going to trial a 'ref-cam' during the televised chapionship game between Newcastle Falcons and London Scottish this Sunday. It will offer a new perspective for viewers, who can already hear the ref via a microphone, and will provide an additional tool which can be utilised within the development of referees.
