We describe a face modelling tool allowing image representation in a high-dimensional morph space, compression to a small number of coefficients using PCA [1], and expression transfer between face models by projection of the source morph description (a parameterisation of complex facial motion) into the target morph space. This technique allows creation of an identity-blended avatar model whose high degree of realism enables diverse applications in visual psychophysics, stimulus generation for perceptual experiments, animation and affective computing.
