An efficient algorithm for kernel discriminant analysis is developed, which applies the maximal Fisher criterion value and the minimal statistical correlation between feature vectors. In some sense, the proposed algorithm is a generalisation of Xu's method as a nonlinear feature extraction method. Experiments on ORL face database demonstrate that the proposed algorithm is effective.
