Quality Enhancement for Hybrid 3DTV with Mixed Resolution Using Conditional Replenishment Algorithm

다국어 초록 (Multilingual Abstract)

This paper proposes a conditional replenishmentalgorithm (CRA) to improve the visual quality (wherespatial resolutions of the left and right views aremismatched) of a hybrid stereoscopic 3DTV that is basedon the ATSC-M/H standard. So as to generate anenhanced view, the CRA is to choose the better substituteamong a disparity-compensated view with high qualityand a simply interpolated view. The CRA generates adisparity map that includes modes and disparity vectorsas additional information. It also employs a quad-treestructure with variable block size by considering thespatial correlation of disparity vectors. In addition, it takesadvantage of the disparity map used in a previous frameto keep the amount of additional information as small aspossible. The simulation results show that the proposedCRA can successfully improve the peak signal-to-noiseratio of a poor-quality view and consequently have apositive effect on the subjective quality of the resulting 3Dview.
