PROJECT TITLE :
Error-Resilient and Error Concealment 3-D SPIHT for Multiple Description Video Coding With Added Redundancy
During this paper, we present a multiple description video coding algorithm based mostly on error-resilient and error concealment set partitioning in hierarchical trees (ERC-SPIHT). During this proposed approach, additional redundancy is generated by wavelet decomposing the spatial root subband and such redundancy is then intentionally inserted into the substreams. Thence, the novelty of the proposed approach is that the basis subband coefficients lost during transmission in any substream can be reconstructed by exploiting each inherent redundancy and inserted redundancy. This reconstruction procedure is implemented in 2 steps, 1st by using existing a pair of-D error concealment techniques, and second with the proposed root subband recovery approach. The former step is employed to estimate the missing coefficients in the spatial root and high frequency subbands by exploiting the inherent redundancy, while the latter attempts to utilize the inserted redundancy to additional improve the precision in the estimation of the missing spatial root subband coefficients. The proposed root subband recovery technique will be iteratively applied and accuracy of the reconstruction can be gradually increased with every iteration. Experimental results on completely different video sequences show that the proposed methodology maintains error-resilience with high coding efficiency. In explicit, our results demonstrate that the proposed algorithm achieves a vital improvement on video quality by up to a pair of.5753 dB within the presence of a substream loss compared to ERC-SPIHT.
