EIGENFEATURES AS INTERMEDIATE-LEVEL REPRESENTATIONS - THE CASE FOR PCA MODELS

Eigenfeatures are created by the principal component approach (PCA) us ed on objects described by a low-level code (i.e., pixels, Gabor jets) . We suggest that eigenfeatures act like the flexible features describ ed by Schyns et al. They are particularly suited for face processing a nd give rise to class-specific effects such as the other-race effect. The PCA approach can be modified to accommodate top-down constraints.
