In this paper, a new face recognition system based on Wavelet transform (HWT) and Principal Component Analysis (PCA) is presented.The image face is preprocessed and detected.The Haar wavelet is used to form the coefficient matrix for the detected face.The image feature vector is obtained by computing PCA for the coefficient matrix of DWT.A comparison between the proposed recognition system using DWT, PCA and Discrete Cosine Transform (DCT) is also made.
