In this paper, we propose a generic error resilient video coding (ERVC) scheme using embedded Wyner-Ziv (WZ) description. At the encoder side, a joint source-channel R-D optimized mode selection (JSC-RDO-MS) algorithm with WZ-coded anchor frames is statistically studied and developed. Given a stationary first-order Markov Gaussian source, the proposed mode optimization is justified by an analysis...
Traditional multiview video coding schemes exploit all types of correlations at the encoder. The inherent high encoder complexity and the needs for large volume data communication between cameras make them impractical for many applications. In this paper, we propose a novel distributed coding scheme for multiview video. All the views are separately encoded but jointly decoded. At the decoder, we design...
In this paper, we investigate a fundamental issue in the distributed video coding (DVC) that, once resolved, would substantially improve the compression efficiency in DVC. This fundamental issue is the underlining relation between the distribution of the prediction errors and the compression efficiency of DVC. In the current approach to DVC, after the construction of prediction frame at decoder, the...
In this paper, we propose a suite of efficient schemes for the representation of spatial and temporal correlations of video signals in distributed video coding (DVC). These schemes consist of zero motion skipping, Gray codes, and sign bits coding of DCT coefficients developed to improve the overall rate-distortion (R-D) performance of distributed video coding. Existing schemes have focused on exploiting...
