noun. A related set
of facial characteristics that a computer uses to
recognize a person's face.
"Since no two people on
this planet of more than 4 billion look exactly
alike, you might think that there must be millions
of ways in which faces differ from one another.
Not so, Pentland says. Faces actually vary
according to a mere 100 factors....Yet the
computer must understand what these 100 factors
are. Pentland fosters such understanding through
the use of a technique whereby each face image is
deconstructed into separate eigenfaces, a
word derived from the German prefix eigen, meaning
'own' or 'individual.' "
