Robust 3-D Video System Based on Modified Prediction Coding and Adaptive Selection Mode Error Concealment Algorithm

To improve the quality of 3D Multi-View Video (MVV) transmitted over noisy channels, we deploy Modified Prediction Multi-view Video Coding (MPMVC) algorithm at the encoder and Adaptive Selection Mode Error Concealment (ASMEC) algorithm at the decoder. MPMVC scheme exploits the best available correlations between video streams to construct the optimum MVC prediction structure. Deploying MPMVC at encoder can make the transmitted 3D MVV very robust to severe channel errors through aiding the proposed ASMEC algorithm to mitigate error propagation. To further improve the decoded MVV quality without increasing transmission rates, we deploy ASMEC algorithm at the decoder that can exploit the spatial, temporal and inter-view correlations in concealing transmission errors. Our results show that the proposed MPMVC-ASMEC schemes jointly improve the objective and subjective quality of reconstructed 3D multi-view video sequences and are more robust to transmission errors.
