Family Resemblance in Faces

“Being able to see the family resemblance between faces that have some underlying difference, such as the difference between male and female faces, is an ability that is not well understood and merits further investigation to work out how visual information about faces is organized,” says author Harry J.

As described in the paper “Relative faces: Encoding of family resemblance relative to gender means in face space” researchers conducted two experiments using original and synthesized cross-gender “sibling” faces that resemble each other and “anti-sibling” faces that have the opposite characteristics of the original face.

Possible pairings included a face with its synthesised opposite-gender sibling, a face with its opposite-gender anti-sibling, and a face with a randomly selected opposite-gender face.

“Understanding how we encode faces can inform computer scientists who are building face recognition systems for security applications and computer graphics teams building synthetic faces for applications in the film and gaming industry and to enhance human computer interaction,” added computer scientist and team member Peter McOwan from Queen Mary, University of London.
