problems with a large number of dimensions like face recognition. Nevertheless, classical
PCA is based on L2-Norm which is very sensitive to noises. Recently, a new robust PCA
approach has been proposed by replacing L2-Norm with L1-Norm (PCA-L1). However, PCA-
L1 requires a lot of time to calculate the projection bases. To solve this problem, we propose
to use a wavelets feature extraction method as pre-processing step to face recognition …
