Advanced residual predction in 3D-HEV

Inter-view residual prediction (IVRP) is employed to efficiently code non-base texture views by exploiting the correlation of residues between two views in 3D video coding extension of HEVC(3D-HEVC). To further improve the performance of texture coding, advanced residual prediction (ARP) is proposed in this paper. In IVRP, residues in a non-base view are predicted from decoded residues in base view. In contrast, ARP makes the residual predictor for the non-base view block based on newly generated base-view residues by applying motion vector at the non-base view to the baseview. Moreover, an adaptive weighting factor is applied to reduce prediction error. Comprehensive simulations show that up to 6.0% luma BD-rate reduction was obtained over IVRP in the reference software of 3D-HEVC.
