Texture classification based low order local binary pattern for face recognition

Local Binary Pattern (LBP) represents a circular derivative pattern generated by the concatenation of the binary gradient directions. However, the pattern fails to extract more detailed information such as texture feature contained in the input object. In this paper, we propose a texture classification based low order LBP for face recognition. With the texture feature, we could apply this method only on eye regions rather than whole face image to reduce the computation complexity and recognition time. The experiment result shows the face recognition rate of our approach is better than the original LBP method and the average executing time ratio of proposed method to original LBP method is only 16.3%.
