LBP and CNN feature fusion for face anti-spoofing.

Face anti-spoofing has been attracting attention because of its prominent role in the security of face recognition systems. A face spoofing attack is launched on the authentication system by the attacker using the picture or video of the genuine user to get access to the services or information. This paper proposes local binary pattern (LBP) and convolutional neural network (CNN) based feature fusion model for classifying spoof face images. Initially, the images are pre-processed to remove the effect of the background in the feature extraction. The Viola-Jones algorithm is used for detecting and cropping the faces from the images. The color features of the pre-processed RGB images and LBP features are provided to the CNN. This feature combination reduces the requirement of a CNN-based deep learning architecture for providing a good classification performance. To validate the proposed model, it is trained and tested on NUAA and MSU-MFSD datasets. The experiment recorded the ACER of 0.21 and 0.20 on the MSU-MFSD and NUAA datasets, respectively.
