Abstract
Due to low resolutions of infrared face image, the local texture features are more appreciated for infrared face feature extraction. To extract rich facial texture features, infrared face recognition based on local binary pattern (LBP) and center-symmetric local derivative pattern (CS-LDP) is proposed. Firstly, LBP is utilized to extract the first order texture from the original infrared face image; Secondly, the second order features are extracted CS-LDP. Finally, an adaptive weighted fusion algorithm based separability discriminant criterion is proposed to get final recognition features. Experimental results on our infrared faces databases demonstrate that separability oriented fusion of LBP and CS-LDP contributes complementary discriminant ability, which can improve the performance for infrared face recognition
