abstract = "Multivariate statistical approaches have played an important role
of recognising face images and charac-terizing their differences.
In this paper, we introduce the idea of using a two-stage
separating hyper-plane, here called Statistical Discriminant Model
(SDM), to interpret and reconstruct face images. Analogously to
the well-known Active Appearance Model proposed by Cootes et. al,
SDM requires a previous alignment of all the images to a common
template to minimise varia-tions that are not necessarily related
to differences between the faces. However, instead of using
landmarks or annotations on the images, SDM is based on the idea
of using PCA to reduce the dimensionality of the original images
and a maximum uncertainty linear classifier (MLDA) to characterise
the most discrimi-nant changes between the groups of images. The
experimental results based on frontal face images indicate that
the SDM approach provides an intuitive interpretation of the
differences between groups, reconstructing characteristics that
are very subjective in human beings, such as beauty and
happiness.",
