摘要： A temporal information integration dis-occlusion system and method for using historical data to reconstruct a virtual view containing an occluded area. Embodiments of the system and method use temporal information of the scene captured previously to obtain a total history. This total history is warped onto information captured by a camera at a current time in order to help reconstruct the dis-occluded areas. The historical data (or frames) from the total history match only a portion of the frames contained in the captured information. This warping yields warped history information. Warping is performed by using one of two embodiments to match points in an estimation of the current information to points in the captured information. Next, regions of current information are split using a classifier. The warped history information and the captured information then are merged to obtain an estimate for the current information and the reconstructed virtual view.

摘要： Several implementations relate, for example, to depth encoding and/or filtering for 3D video (3DV) coding formats. A sparse dyadic mode for partitioning macroblocks (MBs) along edges in a depth map is provided as well as techniques for trilateral (or bilateral) filtering of depth maps that may include adaptive selection between filters sensitive to changes in video intensity and/or changes in depth. One implementation partitions a depth picture, and then refines the partitions based on a corresponding image picture. Another implementation filters a portion of a depth picture based on values for a range of pixels in the portion. For a given pixel in the portion that is being filtered, the filter weights a value of a particular pixel in the range by a weight that is based on one or more of location distance, depth difference, and image difference.

摘要： Various implementations address depth coding and related disciplines. In one particular implementation, a segmentation is determined for a particular portion of a video image in a sequence of video images. The segmentation is determined based on reference depth indicators that are associated with at least a portion of one video image in the sequence of video images. Target depth indicators associated with the particular portion of the video image are processed. The processing is based on the determined segmentation in the particular portion of the video image. In another particular implementation, a segmentation is determined for at least a given portion of a video image based on depth indicators associated with the given portion. The segmentation is extended from the given portion into a target portion of the video image based on pixel values in the given portion and on pixel values in the target portion.
