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.”

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.

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...
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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
