【Abstract】 The design of classifier has significant influence upon image recognition.Based on Huang′s recognition methods,class of more comprehensive membership functions are defined in this paper.According to the projection operator theory and the subspace methods,the properties of the membership functions are theoretically analyzed.It is proved that the functions have some good properties and the designed classifiers based on the functions are quadric nonlinear separable.Finally,the whole process from feature extraction to recognition is designed and applied to face recognition.Experimental results show that the proposed methods are effective and feasible.更多还原
