In this paper, a coarse-to-fine, LDA-based face recognition system is proposed. Through careful implementation, we found that the databases adopted by two state-of-the-art face recognition systems[1,2] were incorrect becasue they mistakenly use some non-face portions for face recognition. Hence, a face-only database is used in the proposed system. Since the facial groans on a human face only differe slightly from person to person, the decision-boundary determination process is tougher in this system than it is in conventional approaches.
