Title: Temporal and Inter-view Consistent Error Concealment Technique for Multiview plus Depth Video Broadcasting, accepted in IEEE Transactions on Circuits and System for Video Technology (J11)
Abstract: Multiview plus depth (MVD) is an emerging video format with many applications, including 3D television and free viewpoint television. During broadcast of MVD video, trans- mission errors may cause the loss of whole frames, resulting in significant degradation of video quality. Error concealment techniques have been widely used to deal with transmission errors in video communication. However, the existing solutions do not address the requirement that the reconstructed frames be consistent with other frames. We propose a consistency model for error concealment of MVD video that allows to maintain a high level of consistency between frames of the same view (temporal consistency) and those of the neighbouring views (inter-view consistency). Simulations with the reference software for the Multiview Video Coding (MVC) project of the Joint Video Team (JVT) of the ISO/IEC Moving Pictures Experts Group (MPEG) and the ITU-T Video Coding Experts Group (VCEG) show that our technique outperforms two standard error concealment techniques with respect to both reconstruction quality and view consistency.
