Spatially enhanced local binary pattern
The local binary pattern (LBP) is one of the state-of-the-art texture descriptors for texture classification. However, the spatial distribution of the LBPs is not taken into account. Proposed is a novel texture descriptor, namely the spatially enhanced LBP, to encapsulate the spatial distribution of the LBPs with a shape context based method. Also, the shape context based method is adapted to be rotation invariant. Experimental results on three widely used benchmark datasets show that the proposed descriptor outperforms the original LBP descriptor.
