In this paper a novel independent component analysis (ICA) based face super-resolution algorithm is proposed. In this scheme, the independent components (ICs) are obtained by offline training high-resolution face images. Given a low-resolution image, the high-resolution image is reconstructed by the linear combination of the ICs where the weight coefficients are obtained by the method of maximum a posteriori (MAP). The prior of ICA coefficients are estimated by performing PCA on training images… CONTINUE READING
