Abstract

We propose a face difference model that decomposesface difference into three components, intrinsicdifference, transformation difference, and noise. Usingthe face difference model and a detailed subspace analysison the three components we develop a unified frameworkfor subspace analysis. Using this framework we discoverthe inherent relationship among different subspacemethods and their unique contributions to the extractionof discriminating information from the face difference.This eventually leads to the construction of a 3Dparameter space that uses three subspace dimensions asaxis. Within this parameter space, we develop a unifiedsubspace analysis method that achieves better recognitionperformance than the standard subspace methods on over2000 face images from the FERET database.
