Abstract

As the vital component of a recently developed stochastic modelbased feature generation scheme, Fisher score is increasingly usedin classification applications. In this work we present ageneralization of previous proposed feature generation schemes byintroducing the concept of multi-class mapping which is oriented tomulti-class classification problems. Based on the generalizedfeature generation scheme, a novel face recognition system isdeveloped by a systematical integration of hidden Markov model(HMM) and linear discriminant analysis (LDA).The proposed system isevaluated on a public available face database of 50 subjects.Comparing to holistic features based LDA method, stand alone HMMmethod, and LDA method basedon previous proposed feature generationschemes which are intrinsically oriented to two-class problems,superior performance is obtained by our method in terms ofrecognition accuracy.
