Face recognition using illuminant locality preserving projections

A novel supervised manifold learning method was proposed to realize high-accuracy face recognition under varying illuminant conditions.The proposed method,named illuminant locality preserving projections(ILPP),exploited illuminant directions to alleviate the effect of illumination variations on face recognition.The face images were first projected into low-dimensional subspace.Then the ILPP translated the face images along specific direction to reduce lighting variations in the face.The ILPP reduced the dis...
