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 is provided, having: an extractor configured to respectively extract, from the multi-view data signal, for sub-regions of the frames of the second-view video, a disparity vector and a prediction residual; a predictive reconstructor configured to reconstruct the sub-regions of the frames of the second-view video, by generating a prediction from a reconstructed version of a portion of frames of the first-view video using the disparity vectors and a prediction residual for the respective sub-regions; and an intermediate view synthesizer configured to reconstruct first portions of the intermediate view video.

1. A hybrid video decoder comprising:
an extractor configured to:
receive a multi-view data comprising information on a first view video and a second view video;determine, from the received multi-view data, a disparity vector and a prediction residual associated with a sub-region of a frame of the second view video, wherein the sub-region of the second view video is associated with an inter-view prediction mode; andgenerate, based on the multi-view data, a reconstructed version of a portion of a frame of the first view video based on an inverse transformation; a predictive reconstructor configured to:
receive, from the extractor, the reconstructed version of the portion of the frame of the first view video; andreconstruct the sub-region of the frame of the second view video from the reconstructed version of the portion of the frame of the first view video using the disparity vector and the prediction residual extracted from the multi-view data; and a view synthesizer configured to reconstruct a first portion of a frame of a third view video using the reconstructed version of the portion of the frame of the first view video and the disparity vector.
