Local binary pattern (LBP) and its variants have been widely used in many visual recognition tasks. Most existing approaches utilize predefined LBP structures to extract LBP features. Recently, data-driven LBP structures have shown promising results. However, due to the limited number of training samples, data-driven structures may overfit the training samples, hence could not generalize well on the novel testing samples. To address this problem, we propose two structural regularization constraints for LBP-structure optimization: symmetry constraint and uniformity constraint. These two constraints are inspired by predefined LBP structures, which convey the human prior knowledge on designing LBP structures. The LBP-structure optimization is casted as a binary quadratic programming problem and solved efficiently via the branch-and-bound algorithm. The evaluation on two scene-classification datasets demonstrates the superior performance of the proposed approach compared with both predefined LBP structures and unconstrained data-driven LBP structures.
