This manuscript presents, Face
recognition by combining different extraction
approaches combining PCA (principal Component
Analysis), DWT (Discrete wavelet transform
neural networks. This method consists of four
steps: i) Preprocessing, ii) Dimension reduction
using DWT, iii) feature extraction using PCA and
iv) classification using neural network. To validate
this work, we have tested this technique on frontal
images of the ORL and Yale databases
