英文摘要：

Objective Local Binary Pattern （LBP） is a theoretically simple yet highly efficient texture descriptor. LBP has recently attracted increasing attention and has been successfully applied in image analysis, computer vision, and pattern recognition because of its discriminative power and computational simplicity. LBP has been developed＇for the traditional pattern recognition problems of texture classification and face recognition. Considering the theoretical and practical values of LBP, this study comprehensively reviews the suitability of various LBP variants in texture classification and face recogni- tion. Method The fundamentals of the traditional LBP and various LBP variants are reviewed, and the advantages and dis- advantages of various LBP variants are discussed by dividing them into categories under a novel systematic framework. Im- plicit directions for future LBP studies are also presented. Result First, the fundamentals of the traditional LBP method and various LBP variants are reviewed in detail and the pros and cons of various LBP variants are discussed by dividing them in- to different categories under a novel systematic framework. Second, as two typical and most successful applications of the LBP approach, LBP-based texture classification and LBP-based face recognition are reviewed. Finally, the implicit direc- tions for future LBP research are presented. Conclusion LBP method continues to be a hot research topic in the field of computer vision and pattern recognition, which is evidenced by the fact that new low storage and fast local binary descriptors and new applications of LBP are still emerging.
