Upload 'Average' Photo For Better Smartphone Recognition
However, performance could be greatly improved, often to perfect levels, if users stored an 'average' of their own photos -- formed by morphing together several different photos of the user.
"We expect this technique to work across a wide range of phones and other automated recognition devices. It is very interesting that performance can be so much improved by copying a simple trick performed by the brain," he noted in a paper published in the journal PLOS ONE.
The idea for this technique comes from studies of human face recognition. It is understood that the brain forms abstract representations of the faces it knows, and that people are very good at recognising their family and friends over a range of conditions.
If it is possible to copy these representations, then automatic face recognition can improve.
"Using 'average' images is a simple way to do this," the authors concluded.
