This paper attempts to address these questions by proposing a new local feature extractor to generalize and complete LBP, and we name the proposed method completed LBP (CLBP). In CLBP, a local region is represented by its center pixel and a l

results than conventional LBP based schemes. Several observations can be made for CLBP. First, LBP is a special case of CLBP by using only CLBP_S. Second, we will show that the sign component preserves more image local structural information
