Temporal and Inter-View Consistent Error Concealment Technique for Multiview Plus Depth Video

Error concealment of multi-view video sequences using inter-view and intra-view correlations

An efficient error concealment algorithm for multi-view video sequences is proposed in this work. First, we develop three concealment modes: temporal bilateral error concealment (TBEC), inter-view bilateral error concealment (IBEC), and multi-hypothesis error concealment (MHEC). TBEC and IBEC, respectively, exploit intra-view and inter-view correlations in multi-view video sequences to reconstr...

Error Resilience and Concealment in Multiview Video over Wireless Networks

An Efficient Adaptive Boundary Matching Algorithm for Video Error Concealment

Sending compressed video data in error-prone environments (like the Internet and wireless networks) might cause data degradation. Error concealment techniques try to conceal the received data in the decoder side. In this paper, an adaptive boundary matching algorithm is presented for recovering the damaged motion vectors (MVs). This algorithm uses an outer boundary matching or directional tempo...

Fast Algorithms for Inter-view Prediction of Multiview Video Coding

The compression efficiency and complexity should be simultaneously taken into consideration in Multiview Video Coding (MVC). In order to reduce the complexity while maintaining the efficiency of MVC, we proposed in this paper two algorithms called Adaptive Search Region Adjustment (ASRA) and Adaptive Selection of Inter-view References (ASIR). In ASRA, we simplified the exiting method to obtain ...

Depth-Enhanced Error Concealment for H.264 Video

The H.264 video coding standard, owing to its excellent compression efficiency, has become the key technology of many video applications. But the H.264/AVC video is very vulnerable to data errors or packet losses. In this paper, we propose a new H.264 error concealment technique that exploits the depth relevance between spatially or temporally neighboring blocks. The motion vectors gathered fro...
