| Abstract: | Fisher optimal discriminant is a fundamental method in feature extraction which is an important tache for pattern recognition.A new method for calculating the Fisher optimal discriminant vector is introduced which can be suited to the case that the within-calss scatter matrix is singular,and the calculation step is given.The ideology of this method is succinctness and performance easy. |
