Novel interactive face matching procedure
A research team from Nottingham Trent University, the University of Birmingham, the University of Greenwich, and the University of New South Wales has trialled a new interactive viewing procedure for face matching.

This new procedure supplies users with an interactive image of a face that they can rotate to different orientations. The results show that the interactive procedure reliably improved face matching accuracy for both typical and super face recognisers. Perhaps as importantly, the procedure improved accuracy at ruling out mismatching images.
The findings also show that the system even improves correct identification accuracy when image quality is low. As such, this interactive matching system may be particularly helpful in assisting with identification in CCTV images, which often relies on matching footage to mugshots.
Dr Harriet Smith, lead author and independent research fellow in psychology at NTU’s School of Social Sciences, said:
“These findings suggest that providing visual information about how a face looks from different viewpoints reduces human error, which has implications for any context where photo ID is used for identity verification, such as passport processing, border control, surveillance and CCTV.
Super recognisers are people with exceptional face recognition ability. While this skill is rare, some police forces now deploy such people to identification roles to try and mitigate the risk of incorrect face matching decisions. Our results suggest that this risk can be minimised further by using the interactive procedure.”
