Abstract

A face recognition algorithm with optimal features extraction based on particle swarm optimization(PSO)is proposed to enhance the recognition rate. Features of each face image are extracted by using the wavelet transformation and the tensor principal component analysis(PCA)algorithm. Weights of the features' elements are then determined using PSO according to the right clustering rate of each element

so that the object to extract the key features of the faces can be realized. Experimental results on the UMIST database show that the impact of changes in expression

light and posture can be reduced by the proposed algorithm

and that the recognition ratio is increased by 12.75% compared with tensor PCA.
