Abstract:Multi-view video plus depth (MVD) is a new 3D video format that would support 3D application developed by MPEG.Such a format is a combination of texture video and associate d depth maps.Consequently, for the efficient transmission of 3D video signals,the compression of texture a nd depth maps is required to reduce the inter-view correlation,the correlation between texture and the de pth maps as well as the spatio-temporal correlation.Therefore,this makes the compressed bit-streams very sensitive to t ransmission errors and leads to error propagation easier.In order to prevent the error propagation,effective error con cealment (EC) algorithms are necessary.An error concealment method for multi-view video plus depth is propo sed in this paper.Based on the corrections between depth map and texture map and the spatial corrections,the lost macroblocks (MBs) are classified into three types:simple MB,less complex MB and complex MB.Following the classif ication,corresponding operations,including candidate motion vector refinement EC algorithm,depth-bas ed outer boundary matching algorithm and error concealment with adjustable weights,are used to reconstruct the lost MBs.Experimental results show that the proposed method can effectively reduce the complexity of E C algorithm and ensure the video quality at the same time.
