HYBRID VIDEO CODING SUPPORTING INTERMEDIATE VIEW SYNTHESIS

摘要

Hybrid video decoder supporting intermediate view synthesis of an intermediate view video from a first- and a second- view video which are predictively coded into a multi-view data signal with frames of the second-view video being spatially subdivided into sub-regions and the multi-view data signal having a prediction mode out of a set of possible prediction modes, associated with each of the sub-regions, wherein the set of possible prediction modes comprises at least an inter-view prediction mode and an intra-view prediction mode, the hybrid video decoder comprising: an extractor configured to respectively extract, from the multi-view data signal, for sub-regions of the frames of the second-view video with which the inter-view prediction mode is associated, a disparity vector and a prediction residual; a predictive reconstructor configured to reconstruct the sub-regions of the frames of the second-view video with which the inter-view prediction mode is associated, by generating a prediction from a reconstructed version of a portion of frames of the first-view video using the disparity vectors extracted from the multi-view data signals for the respective sub-regions, and a prediction residual for the respective sub-regions; and an intermediate view synthesizer configured to reconstruct first portions of the intermediate view video using the reconstructed version of the portions of the frames of the first-view video, and disparity vectors extracted from the multi-view data signal.
