In the robust principal component analysis(RPCA)model
the statistical properties of every variable are neglected when scale parameters are chosen for them.In order to overcome this drawback
a generalized robust principal component analysis(GRPCA)model was proposed in this paper
a M-estimator was adopted to estimate robust scale parameters for every variable according to their statistical properties.Then
a new independent component analysis algorithm for face recognition based on wavelet decomposition and robust estimation (WR-ICA) was proposed.WR-ICA is robust to many types of outliers (incomplete face image
making up
occlusion
etc).The validity of WR-ICA is confirmed by theory analysis and experimental data
