Discriminative color descriptor by the fusion of three novel color descriptors

This work introduces three color descriptors i.e. Color LBP (CLBP), Color HELBP (CHELBP) and Color LPQ (CLPQ). Precisely LBP, HELBP and LPQ are applied separately on RGB color compo-nents. Then all component features are joined for forming size of respective color descriptor. Further CLBP, CHELBP & CLPQ are joined to build robust face representation Discriminative Color Descriptor (DCD). Color descriptors shows their potency than gray ones and DCD conquer gray & color descriptors. DCD also outperforms several literature techniques.
