EAST LANSING, Mich. – Michigan State University researchers received a $12 million, four-year federal grant from the Intelligence Advanced Research Projects Activity, or IARPA, under its Biometric Recognition and Identification at Altitude and Range, or BRIAR, program.

The IARPA BRIAR program is a 48-month effort to deliver end-to-end software systems capable of detecting individuals at severe imaging conditions, extracting biometric signatures from the whole-body (such as an individual’s gait and/or body shape) and face, and fusing biometric information for robust multi-modal matching.

The MSU project entitled “Physics-driven Modeling and Learning for Person Recognition at a Distance and Altitude” is led by Xiaoming Liu, an MSU Research Foundation Professor; Arun Ross, Martin J. Vanderploeg Endowed Professor; and Anil Jain, a University Distinguished Professor — all in the College of Engineering.

Biometric recognition refers to technology for real-time and automated recognition of individuals based on their body attributes such as face, fingerprints and iris. We use biometrics when we unlock our mobile phones using face or fingerprints, board international flights and go through immigration after returning from an overseas trip. In these applications, the camera or sensor needs to be in close proximity to the individual being recognized. But what about situations when law enforcement agencies want to find a missing person in the woods or locate a group of fugitives?

The MSU BRIAR team incorporated the use of drone technology for recognizing individuals at a distance. While the elevated imaging platforms increased the altitude and range, this vantage point often only showed the tops of people’s heads, making it difficult to identify any distinguishing facial features from one person to another. 

This, according to Liu, necessitated the use of whole-body biometric recognition. “When we combined the benefits of each of the three biometric modalities (face, body shape and gait), we were able to achieve state-of-the-art accuracy as reported in the independent evaluation conducted by IARPA on sequestered data,” he said.

MSU’s system, called FarSight, accepts videos from drones as input and outputs a candidate list of identities from a database. To build this prototype system, the MSU team had to address a number of challenges, including low-quality imagery, atmospheric turbulence, large variations in viewing angle and distance, and limited amount of operational data to train the recognition system. 

“We have developed a successful protype system that can look at one person from about 300 to 400 meters away,” said Liu. “During the next phase of the project, we’ll be looking at multiple people together at a range of 600 to 700 meters.

As the team improves the range and accuracy of the system, it is also learning the relative strengths of various biometric measurements in images captured at different viewpoints. 

“We were surprised to learn that a person’s height, build and gait often contain more useful biometric information than their face when capturing images from a long distance,” said Liu.  

MSU’s team, which serves as the lead institution for this project, also includes Christopher Perry in the Department of Computer Science and Erin Bunting and Robert Goodwin in MSU’s Remote Sensing and Geographic Information Systems Center. Other researchers and personnel for the project include Stanley Chan at Purdue University, Atlas Wang at the University of Texas at Austin and Humphrey Shi at the Georgia Institute of Technology.

Weight loss? ‘Nuting’ to worry about with almonds

Weight loss? ‘Nuting’ to worry about with almonds
2023-09-19
When it comes to weight loss, nuts can get a bad rap – while they’re high in protein, they’re also high in fats, and this often deters those looking to shed a few kilos. But new research from the University of South Australia shows that you can eat almonds and lose weight too.   In the largest study of its kind, researchers found that including almonds in an energy restricted diet not only helped people to lose weight, but also improved their cardiometabolic health.   Examining the effects of energy restricted diets supplemented with Californian almonds or with carbohydrate- rich snacks, researchers found that both diets ...

Patients visiting emergency departments because of alcohol abuse are more likely to make return visits and to die in the following decades

Patients visiting emergency departments because of alcohol abuse are more likely to make return visits and to die in the following decades
2023-09-19
Barcelona, Spain: People who come to emergency departments with alcohol-related diseases or conditions are more likely to make return visits and to die in the following 20 years, than people who come to emergency departments for other reasons, according to new research. For many, this means they may die in their 40s or 50s.   Professor Drew Richardson told the European Emergency Medicine Congress that he and his colleagues had followed 194 patients who had alcohol-related diagnoses when they arrived in the emergency department of The Canberra Hospital ...

Sylvester study shows that new protocols enable many patients to safely return home just one day after lung cancer surgery
2023-09-18
MIAMI, FLORIDA (Sept. 18, 2023) – Thoracic surgeons and researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine found that increasing numbers of patients undergoing cancer-removal lung surgery by “anatomic lung resections” – lobectomies or segmentectomies – are able to go home safely and without complications one day after the operation, thanks to growing rates of robot-assisted surgeries and improvements in patient-centered care protocols. However, the research team found, patients of lower socioeconomic status were considerably ...

Canopy gaps help eastern hemlock outlast invasive insect

2023-09-18
A new study finds that creating physical gaps in the forest canopy give eastern hemlocks more access to resources and help those trees withstand infestation by an invasive insect. The approach adds another tool to the toolkit that foresters can use to protect these trees. Eastern hemlocks are an ecologically important tree species found from eastern Canada to the Great Lakes states and south along the entire Appalachian mountain range. The hemlock woolly adelgid – an invasive insect that was introduced to North America 70 years ago and has spread along the East Coast – can kill a hemlock tree in as little as four years. “An ...

Promising gene-based approaches to repair lethal lung injury in the elderly from COVID-19, pneumonia, flu, sepsis

2023-09-18
Discovery from the lab of Youyang Zhao, PhD, from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago offers promising treatment approaches for acute respiratory distress syndrome (ARDS) in the elderly that can be caused by severe COVID-19, pneumonia, flu or sepsis. Currently there are no pharmacological or cell-based treatments for ARDS. Dr. Zhao’s research established that a gene called FOXM1 is important in the repair of blood vessel through regeneration of endothelial cells, which line the vessels of the lung. He found that aging impairs this gene’s expression, ...
