— An efficient multi-hypothesis error concealment algorithm for H.264 video is proposed in this work. The proposed algorithm temporally conceals a lost block by combining several hypothesis blocks in the previous frame. We investigate the error recovery performance according to the number of hypotheses and the weighting coefficients. Simulation results(More)
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), interview bilateral error concealment (IBEC), and multi-hypothesis error concealment (MHEC). TBEC and IBEC, respectively, exploit intra-view and interview correlations in(More)

A virtual view synthesis algorithm using multi-view video sequences , which inherits the advantages of both the forward warping and the inverse warping, is proposed in this work. First, we use the inverse warping to synthesize a virtual view without holes from the nearest two views. Second, we detect occluded regions in the synthesized view based on the(More)
In this work, we propose an efficient coding algorithm for multi-view video sequences, captured with a 2-D camera array. We develop an efficient prediction structure, which can exploit interview redundancies as well as temporal redundancies in 2-D multi-view video sequences. Moreover, we propose a view interpolation technique based on the bilateral(More)
