摘要： It is presented a method for creating a disocclusion map used for coding a three- dimensional, 3D, video, the method comprises receiving (800) a pixel-based disocclusion map in which pixels are marked either as disoccluded or not. A block- based disocclusion map is derived (802) based on the pixel-based disocclusion map. An area of the block-based disocclusion map that has been marked as disoccluded is extended (804). It is also presented an encoder (30), a decoder (32) and a system for creating the disocclusion map.

摘要： In a method for extracting information from an encoded bit stream, the extracted information may be used for improving bit stream quality assessment, or for adapting a decoding sub-system. From an encoded bit stream, received from a bit stream source, complexity related information that is indicative of the complexity of the encoding of said bit stream is extracted. On the basis of said extracted complexity related information one or more data settings are then selected, after which the data settings may be used as an input for improving bit stream quality assessment at a decoding device or a network node, or for adapting a bit stream decoding sub-system at a decoding device.
