Low-dimensional procedure for the characterization of human faces

J Opt Soc Am A. 1987 Mar;4(3):519-24. doi: 10.1364/josaa.4.000519.


A method is presented for the representation of (pictures of) faces. Within a specified framework the representation is ideal. This results in the characterization of a face, to within an error bound, by a relatively low-dimensional vector. The method is illustrated in detail by the use of an ensemble of pictures taken for this purpose.
