Appearance-based approach is one of popular methods for face analysis. How to describe face appearance is a key issue for appearance based face analysis. Principal component analysis (PCA) and independent component analysis (ICA) are two successful and well-studied linear unsupervised representation methods of face appearance. However, there exist complicate nonlinear variations in real face images due to pose, illumination, expression variations and so on, so it is inadequate for PCA and ICA… CONTINUE READING
