This letter develops a simple and effective whitening method for flattening the power-law power spectrum of face images and combines the whitening technique and PCA/ICA for face recognition. The whitening parameter in the whitening filter is adaptive to the input data so as to make the power spectrum of the whitened results as flat as possible. This proposed method is computationally saving for using fast Fourier transform algorithms. The transformed ldquowhitenedfacesrdquo are applied to face… CONTINUE READING
