Looking upon the patches of face images as some specific class of signals, their eigen-subspace can be found by Principal Components Analysis, and the super-resolved facial patches are regularized in the orthogonal complement of the eigen-subspace. This eigen-subspace based regularization is combined with the classic reconstruction constraint under a Bayesian framework to produce the high-resolution outcome.
