A new algorithm is proposed for face recognition by a Bayesian framework.Posterior distributions are computed by Markov chain Monte Carlo (MCMC).Face features used in the paper are those used in our previous work[A Unified Approach to Video Face Detection, Tracking and Recognition][Partial automation of database acquisition in the FAVRET face tracking and recognition systemusing a bootstrap approach] based on the Elastic Graph Matching method. While our previous method attempts to optimize facial feature point positions so as to maximize a similarity function between each model and face region in the input sequence, the proposed approach evaluates posterior distributions of models conditioned on the input sequence. Experimental results show a rather dramatic improvement in robustness.The proposed algorithm eliminates almost all identification errors on sequences showing individuals talking, and reduces indentification errors by more than 90% on sequences showing individuals smiling although such data was not used in training.
