We propose a new kernel direct discriminant analysis (KDDA) algorithm in this paper. First, a recently
advocated direct linear discriminant analysis (DLDA) algorithm is overviewed. Then the new KDDA
algorithm is developed which can be considered as a kernel version of the DLDA algorithm. The
design of the minimum distance classifier in the new kernel subspace is then discussed. The results of
experiments on two well-known facial databases show the effectiveness of the proposed method in face
recognition. The results of experiments also confirm that DLDA can be viewed as a special case of the
proposed KDDA algorithm.
