Abstract:Based on Fisher's discriminant function, Foley Sammon's optimal set of discriminant vectors has great influence in the area of pattern recognition. A general rule for feature extraction is to extract features as uncorrelated as possible, but the discriminant vectors in Foley Sammon's optimal set are correlated. In the paper here, an optimal set of uncorrelated discriminant features is presented, and some formula to compute it is given. Experiments with ORL face image database have been performed. Experimental results show that new optimal set of uncorrelated discriminant features has powerful ability of feature extraction, and is superior to Foley Sammon's optimal set of discriminant vectors.
Keywords:Pattern recognition  feature extraction  discriminant analysis  face recognition
