Face-recognition technology has identified unknown World War I soldiers in photos, more than 100 years after the photos were taken.

The world-first project by the Australian War Memorial (AWM) and tech company NEC Australia used the technology to match unknown soldiers photographed in 1916 in France to already identified soldiers in the AWM photo collection.

The photos of the previously unidentified soldiers were taken by husband and wife photographers the Thuilliers, in their home village of Vignacourt, a rest stop for soldiers just behind the Western Front battle lines in Northern France.

The images are on glass negatives* and were some of almost 4000 uncovered in a wooden chest in the attic of the Thuillier’s former farmhouse in 2011.

AWM considers it to be one of the most precious visual records reflecting the service and sacrifice of Australian soldiers in World War I.

Kerry Stokes presented a collection of fragile First World War photographic glass plates to the Australian War Memorial. These plates form part of the Louis and Antoinette Thuillier Collection, uncovered in 2011 after sitting undisturbed for nearly a century in the attic of a farmhouse in the French town of Vignacourt. Mr Stokes is donating more than 800 of these glass-plate negatives, which feature Australian soldiers in informal settings. media_cameraOne of the collection of fragile World War I glass negatives found in the attic in a farmhouse in Vignacourt.

Australian businessman Kerry Stokes — also the chairman of AWM — bought 800 of the negatives — known as the Vignacourt or Thuillier Collection — and donated them to the war memorial.

Unfortunately, none of the people in the photos was able to be identified at the time of the Vignacourt Collection’s discovery.

A national touring exhibition called “Remember Me: the lost Diggers* of Vignacourt” uncovered a handful of potential identifications.

At the time of the exhibition, AWM curator Joanne Smedley talked about the difficulty of identifying the men without face-recognition technology.

“Identifying the men can often be a slow and challenging process,” Ms Smedley said in an interview published on the AWM website.

“Once you put people in a uniform, and you put a hat on, and you turn your face in different angles, your face can look remarkably different.”

NEC Australia used face-recognition technology in a two-day trial, making many potential matches.

The first of these was Private Robert Deegan, a young soldier from Bendigo, Victoria who was photographed by the Thuilliers in Vignacourt in 1916 and a year earlier at a recruitment station in country Victoria. The resemblance* was clear.

“NEC was honoured to be invited to join the AWM in this really worthwhile project,” said NEC’s David Borean.

“All Australians are aware of our nation’s proud military past, in particular our service in World War I and to be able to successfully uncover Diggers* whose identities remained a mystery for almost a century was not only exciting, but a great privilege.

“The dedicated research team at the AWM has spent many hours working to manually identify Diggers from the Vignacourt collection over almost a decade against other collections it had in its archives*.

“So to be able to help them identify previously unknown soldiers in a matter of hours was a thrill for us as an organisation,” Mr Borean said.

HOW DOES FACE-RECOGNITION TECHNOLOGY WORK?
Face-recognition or facial-recognition technology is used by some governments, spy agencies and police to find and identify people in a crowd.

Versions of the technology are used by social media platforms such as Facebook to help people tag photos. It is also available on some smartphones.

The technology works using artificial intelligence. First, the technology learns what a face is by training using many, many photos.

Different versions of the technology work in different ways, but once the technology has learned what a face is, it then works on telling different faces apart by measuring and mapping facial features.

Once the computer has a face map for a particular person, it can measure a new image to see if it’s a match.
