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 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： The present invention relates to three dimension (3D) scene representations and in particular to a method and a processor for providing improved 3D scene representations. An objective of the embodiments of the present invention is to improve the determination of consistency among a plurality of projections at a virtual view denoted vF. When determining the consistency, entries of a distance matrix, indicative of distance differences of 3D components between different views for a corresponding segment k when projected to the predefined view (vF) for each segment k, are compared with entries of a threshold matrix. The objective is achieved by assigning each segment k of a 3D component to a cluster based on individual rules for each cluster and one threshold matrix and by determining one threshold matrix for each cluster based on the segments of that cluster.

摘要： Co-processing of a video frame (32) and its associated depth map (34) suitable for free viewpoint television involves detecting respective edges (70, 71, 80, 81) in the video frame (32) and the depth map (34). The edges (70, 71, 80, 81) are aligned and used to identify any pixels (90-92) in the depth map (34) or the video frame (32) having incorrect depth values or color values based on the positions of the pixels in the depth map (34)or the video frame (32) relative an edge (80) in 5 the depth map (34) and a corresponding, aligned edge (70) in the video frame (32). The depth values or color values of the identified pixels (90-92) can then be corrected in order to improve the accuracy of the depth map (32) or video frame (34).

摘要： Method and arrangement for increasing the resolution of a depth or disparity map related to multi view video. The method comprises deriving a high resolution depth map based on a low resolution depth map and a masked texture image edge map. The masked texture image edge map comprises information on edges in a high resolution texture image, which edges have a correspondence in the low resolution depth map. The texture image and the depth map are associated with the same frame.

摘要： The present invention relates to three dimension (3D) scene representations and in particular to a method and a processor for providing improved 3D scene representations. An objective of the embodiments of the present invention is to improve the determination of consistency among a plurality of projections at a virtual view denoted νF. When determining the consistency, entries of a distance matrix, indicative of distance differences of 3D components between different views for a corresponding segment k when projected to the predefined view (νF) for each segment k, are compared with entries of a threshold matrix. The objective is achieved by assigning each segment k of a 3D component to a cluster based on individual rules for each cluster and one threshold matrix and by determining one threshold matrix for each cluster based on the segments of that cluster.
