摘要： The method implements an update step which is a selection among at least the following coding modes: a default coding mode which doesn't use the motion compensation for the calculation of the pixel if the pixel is not connected or which performs a low pass motion compensated temporal filtering of picture H of same level if the pixel is connected, an update_MV coding mode which performs a low pass motion compensated temporal filtering of picture H of same level according to a default motion vector calculated by taking into account motion vectors belonging to regions or pixels in the vicinity of the pixel to be calculated. Applications relate to video compression for transmission or storage of data.

摘要： The invention relates to the encoding of visual data captured by two or more cameras in a layered depth format.The invention proposes a method and device for layered s depth image encoding. The device is adapted for encoding at least one occlusion layer of the layered depth image with a greater horizontal width than a foreground layer of the layered depth image. The method comprises a corresponding step. Further, a non-transitory storage medium carrying at least one encoded layered depth image is proposed.The additional horizontal width can be used for conveying the part of information which is provided in the images/videos captured by the at least two cameras but not comprised in the foreground layer.
