ISSN: 2278 1323 International Journal of Advanced Research in Computer Engineering & Technology (IJARCET) Volume 1, Issue 9, November 2012 135 All Rights Reserved 2012 IJARCET Abstract This paper mainly addresses the building of face Recognition system by Using Principal Component Analysis (PCA). PCA is a statistical approach used for reducing the number of variables in face Recognition . In PCA, every image in the training set is represented as a linear combination of weighted eigenvectors called eigenfaces. These eigenvectors are obtained from covariance matrix of a training image set. The weights are found out after selecting a set of most relevant Eigenfaces. Recognition is performed by projecting a test image onto the subspace spanned by the eigenfaces and then classification is done by measuring minimum Euclidean distance.
