New alternatives to 3D body scanning
Researchers from the Max Planck Institute for Intelligent Systems and the University of Texas at Dallas, revealed new crowdshaping technology at SIGGRAPH 2016 that creates accurate 3D body models from 2D photos using crowdsourced linguistic descriptions of body shape.
The Body Talk system takes a single photo and produces 3D body shapes that look like the person and are accurate enough to size clothing. It does this using the help of 15 volunteers who rate the body shape in the photo using 30 words or fewer. The researchers believe this technology has applications in online shopping, gaming, virtual reality and healthcare.
“High-end scanners and their lower-cost alternatives have yet to become ubiquitous in consumer technology,” said Dr. Michael J. Black, Director of the Perceiving Systems Department at the Max Planck Institute for Intelligent Systems. “Capturing 3D body shape remains a challenge, and our goal is to make it easy and fun. Our research shows that people have a shared understanding of body shape that is expressed in our use of language”.

The system uses machine learning to discover this relationship between our verbal descriptions of bodies and their actual 3D shape. ``Language provides rich descriptions of body features related to gender, physical strength, attractiveness, and health“ said Dr. Alice J. O’Toole, Professor in the School of Behavioral and Brain Sciences at the University of Texas at Dallas.
`What is surprising is that language captures 3D shape so accurately and that the collective judgment of the “crowd” can be used to create realistic avatars. This process of crowdshaping opens up a practical way to scan bodies without a scanner” said Dr. Stephan Streuber, the lead author of the study. In the paper, Body Talk: Crowdshaping Realistic 3D Avatars with Words, the researchers found that realistic 3D bodies could be created using as few as ten words.
They demonstrated a “3D paparazzi” application that takes a single photo of a celebrity, has it rated by 15 people, and then creates a 3D avatar of the celebrity that can be animated. They further showed that they can extract measurements from the crowdshaped bodies with an accuracy sufficient for many clothing sizing applications. They even create 3D avatars of characters from books using just the written description.
“When scanning technology is unavailable or inapplicable, Body Talk can be used to visualize mental representations of human body shape,” said Dr. Black. “This system can be used in many areas of science and medicine, for example in studies of body perception disorders, obesity, or cross-cultural attitudes about body shape.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
