摘要： The embodiments of the present invention relates to a method and a processor for representing a 3D scene. In the method, one 3D component of the 3D scene to be represented, captured at least three different views (v1, v2, v3) is projecting to a predefined view (vF). A value associated with each projected view regarding the 3D component is then determined and consistency among the projected views regarding the 3D component is detected. Moreover, a consistency value regarding the 3D component is determined based on the determined values associated with the respective projected view, and the determined values are replaced by the determined consistency value on at least one of the three projected 3D components.

摘要： A scalable video coding method for coding a video sequence (10) results in a bit stream (20} partitionable into two layer representations (201, 2O2) of the video sequence (10). The second layer representation (2O2) has an enhanced resolution compared to the first layer representation (2O1.). The method includes generating (si) predictive coding parameters for the second layer using previously reconstructed pixels (14) in the second layer. The method further includes performing (s2) prediction for the first layer, using the predictive coding parameters and the previously reconstructed pixels (14) in the second layer, to generate a first layer prediction signal. The method further includes generating (s3) a first layer residual, based on the difference between the original image and the first layer prediction signal. The predictive coding parameters and the first layer residual are coded (s4) as the first layer representation (2O1). An encoder (30) and computer program are also provided.

摘要： In one aspect, a compressed video bit stream is received and divided into packets that comprise either video data or supplemental information. Each packet is marked with a first subset identifier associated with a corresponding bit stream subset. A first sequence parameter set (SPS) is marked with the same first subset identifier as its associated bit stream subset. The first SPS comprises a second subset identifier indicating a decoding dependency of the bit stream subset associated with the first subset identifier on a bit stream subset associated with the second subset identifier. In another aspect, the packets from the bit stream are received and the first SPS is extracted. The first and second subset identifiers are used as relevant subset identifiers, and for each received packet, the first subset identifier is inspected and the packet is extracted when the first subset identifier matches one of the relevant subset identifiers.

摘要： An auxiliary information map (10) is upsampled to form an upsampled auxiliary information map (20). Multiple reference pixels (23) in the upsampled auxiliary information map (20) are selected for a current pixel (21) in the upsampled auxiliary information map (20) based on texel values of texels in an associated texture (30). An updated pixel value is calculated for the current pixel (21) based on the pixel values of the selected reference pixels (23).

摘要： The invention relates to a method of generating a synthesized image representing a view of a scene from a first input image representing the view and a second input image representing the view, the synthesized image comprising synthesized image positions, by assigning a synthesized image data value to a synthesized image position. The method comprises determining whether input images have at the synthesized image position data values associated with them. If either one has a data value associated, that data value is assigned to the synthesized image position. If both, an average of both values is assigned. The average is a weighed average, with weighing factors being a function of a distance or distances to a closest image position with no image data value or valid image data value assigned.

摘要： A method of indicating bit stream subsets in a compressed video bit stream is provided. The method comprises receiving the bit stream, dividing the bit stream into packets, wherein each packet comprises either one of video data or supplemental information, marking each packet (310-312, 320-322) with a first subset identifier (s0, s1) which is associated with a corresponding bit stream subset, and providing a first sequence parameter set (SPS) (310), marked with the same first subset identifier as its associated bit stream subset. The first SPS further comprises a second subset identifier (b1) indicating a decoding dependency (304) of the bit stream subset associated with the first subset identifier on a bit stream subset associated with the second subset identifier. Further, a method of extracting video packets from a video bit stream is provided. The method comprises receiving packets from the bit stream, extracting a first SPS (310), which is marked with the first subset identifier (s0) and further comprising the second subset identifier (b1), using the first and the second subset identifier as relevant subset identifiers, and, for each received packet (310-312, 320-322), inspecting the first subset identifier (s0, s1) of the packet, and extracting, under the condition that the extracted first subset identifier matches one of the relevant subset identifiers, the packet from the bit stream.
