Researchers hope to build universal human age estimator

(PhysOrg.com) -- As humans, we have a knack for estimating another person’s age quite accurately just by glancing at their face. Although age estimation may seem relatively simple to us, computers have a much more difficult time performing the task. In one of the latest attempts to build a computer that can accurately estimate a person’s age, researchers have taken a bottom-up approach to the challenge, collecting hundreds of thousands of images and videos from the Internet to train the system. Their goal is to build a universal human age estimator that is applicable to all ethnic groups ...

Harvard group takes complexity out of video face replacement (w/ video)

(PhysOrg.com) -- From Facebook to YouTube to on the fly film projects, the presentation of content that entertains or instructs or both draws on visual tools, ranging from simple to complex. Novice as well as expert creatives are being increasingly equipped with technologies to help them make something creative. Out to prove that point even further, a computer scientist from Harvard University’s School of Engineering and Applied Sciences and colleagues have come up with face-transplant software.

Supercomputers take a cue from microwave ovens

As sophisticated as modern climate models are, one critical component continues to elude their precision—clouds. Simulating these fluffy puffs of water vapor is so computationally complex that even today's most powerful supercomputers, working at quadrillions of calculations per second, cannot accurately model them.

WalkSafe app shields smartphone pedestrians (w/ video)

(PhysOrg.com) -- Smartphone users who as pedestrians are not very smart about crossing and looking both ways now have a protective shield in the form of an Android app which they can download for free. A research team from Dartmouth College and the University of Bologna, Italy, are offering their new app, WalkSafe, which uses the camera on a smart phone to detect oncoming traffic. The phone then alerts the user.

Checkmate! Researchers outsmart Intel copy protection HDCP

For over a decade, Intel's widely used copy protection HDCP has been trusted by the media industry, which carries out business in high-resolution digital video and audio content worth thousands of millions. Researchers from the working group on secure hardware led by Prof. Dr.-Ing. Tim Güneysu of the Ruhr-Universität Bochum were able to checkmate the protection system of an entire industry with relatively little effort using a so-called "man-in-the-middle" attack.
