'Averaging' Faces Could Improve ID Card Security

According to this article, researchers have concluded that ID card photos and passports could be more effect if they depicted averages of several snapshots, so that it will allow a facial recognition software to spot familiar faces as well humans do. Researchers found that humans are much better at recognizing averaged faces than if shown an individual photo. They state and argue that if we see a person from different angles and in varied lighting, we build a mental image of their face that averages out all those experiences.
