dc.description.abstractTransmission errors or packet loss in depth maps have great impact on the decoding quality and view synthesis of 3D and multiview video. Thus efficient methods to recover corrupted depth data are critical functions for accurate view rendering. This paper pro poses an error concealment method for intra-coded depth maps, based on spatial intra and inter-view methods, which exploit neighbouring data of depth and colour images received error-free. A novel three-stage processing algorithm is devised to reconstruct sharp depth transitions (i.e. lost depth contours), using a disparity map and geometric interpolation based on parametric Bezier curves. The simulation results obtained from different views of various MVD sequences, for different packetisation modes and a wide range of packet loss rates (PLR), show that the proposed method consistently leads to quality improvement of synthesised images in comparison with reference methods.eng
