The performance of face recognition is seriously affected by illumination,pose,and expression.To solve this problem,a method for face features extraction and recognition is proposed based on the fusion of cartesian differential invariant(CDI) and LBP.Firstly,an irreducible Cartesian differential invariant set is obtained by combining the differential structure of the face images acquired by using Gauss differential operator.Secondly,by computing and linking all the LBP features of every item in the invarian...
