University develops large-scale 3D facial recognition system
Researchers from The University of Western Australia have designed a new system capable of carrying out large-scale 3D facial recognition that could transform the entire biometrics industry.
The model could be used by any organisation or government agency for more accurate 3D facial recognition and could lead to widespread applications, and improving security measures while potentially removing the need for personal passwords.
Currently, 2D facial recognition of photographs is widely used and has seemingly surpassed human accuracy levels however it has several shortcomings that the more advanced 3D model is able to address.
Unlike 2D facial recognition software, 3D models have the potential to address changes in facial texture, expression, poses and scale, yet the data is difficult to gather.
2D facial data can be obtained simply by searching the internet while 3D facial data requires physical collection from real subjects thereby limiting its use.
The research team from the UWA Department of Computer Science and Software Engineering created the first-of-its-kind model - called FR3DNet - analysing 3.1 million 3D scans of more than 100,000 people.
They trained the model to learn the identities of a large dataset of ‘known’ persons and then match a test face to one of those identities.
The 3D model’s creator, Dr Syed Zulqarnain Gilani, said the model was a huge step forward in the field of 3D facial recognition.
“With off-the-shelf 3D cameras becoming cheap and affordable, the future for pure 3D face recognition does not seem far away,” Dr Gilani said.
“Our research shows that recognition performance on 3D scans is better and more robust. Your 3D scan could be in any pose, wearing glasses or a face mask, and laughing or just smiling and the deep model can recognise you in an instant.
The 3D Facial Recognition model (FR3DNet) is currently available for research purposes. The paper was published in Computer Vision and Pattern Recognition.
