Scientists in Tübingen develop 3D head model that can be used to design better-fitting protective gear


The FLAME model makes it possible to create realistic 3D head shapes capable of accurately mimicking human facial expressions. It could help designers come up with more comfortable protective masks for faces of different shapes and sizes.

Researchers at the Max Planck Institute for Intelligent Systems in Tübingen, Germany have developed a statistical three-dimensional (3D) model of the human head that can be used to design, test, and fit facial protective gear.

FLAME is a statistical 3D head model created from over 30,000 3D head scans using machine learning.

MPI für Intelligente Systeme

The model, called FLAME, allows designers to create strikingly realistic 3D heads corresponding to any type of facial shape. The model can smile, frown, and shout just as people do. The scientists have made FLAME available free of charge to researchers and companies.

“With the COVID-19 pandemic, we’ve seen healthcare workers around the world struggling with ill-fitting protective gear,” says Michael Black, Director at the Max Planck Institute for Intelligent Systems, Head of the Perceiving Systems department, and leader of the project team.

“And as a growing number of communities make mask-wearing mandatory in public life, masks are becoming the new normal. That’s why we see an urgent need for masks that are designed to fit well, and FLAME could be part of the solution.”

To develop FLAME, Black and his team used machine learning to create a head model from over 30,000 detailed 3D scans of real human heads and faces. “FLAME can represent the shape of anyone’s face because it has seen so many different shapes. This makes it an ideal tool for designing facial protective clothing,” says Timo Bolkart, who is a research scientist at the MPI-IS and one of the lead members of the FLAME project team.

“Masks have to fit well to be effective but not everyone has the same shaped face,” Black adds. “Companies sell different sized shoes and clothes, so why do masks come in only one size?” The researchers provide an interactive tool that lets designers explore the natural range of 3D facial shapes and expressions.

The scientists see FLAME as a good example of technology transfer between research and industry. “We see this project as one of many ways in which machine learning and AI can benefit society, and we hope it has a positive impact in addressing the pandemic,” says Black, who is also Speaker of Cyber Valley, Europe’s largest research consortium in the field of artificial intelligence.

Im Focus: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
