摘要： Stereoscopic video data encoded according to a full resolution frame-compatible stereoscopic vide coding process. Such stereoscopic video data consists of a right view and a left that are encoded in half resolution versions in an interleaved base layer and an interleaved enhancement layer. When decoded, the right view and left view are filtered according to two sets of filter coefficients, one set for the left view and one set for the right view. The sets of filter coefficients are generated by an encoder by comparing the original left and right views to decoded versions of the left and right views.

摘要： This disclosure describes techniques for coding 3D video block units. In one example, a video encoder is configured to receive one or more texture components from at least a portion of an image representing a view of three dimensional video data, receive a depth map component for at least the portion of the image, code a block unit indicative of pixels of the one or more texture components for a portion of the image and the depth map component. The coding comprises receiving texture data for a temporal instance of a view of video data, receiving depth data corresponding to the texture data for the temporal instance of the view of video data, and encapsulating the texture data and the depth data in a view component for the temporal instance of the view, such that the texture data and the depth data are encapsulated within a common bitstream.

摘要： A filter unit of a video encoder or video decoder can determine a first metric for a group of pixels within a block of pixels based on a comparison of a subset of the pixels in the block to other pixels in the block; determine a filter based on the first metric; and generate a filtered image by applying the filter to the group of pixels. The subset of pixels can be selected to not include pixels on the boundary of the block of pixels.

摘要： In general, techniques are described for performing motion vector prediction for video coding. An apparatus comprising a motion compensation unit may implement the techniques. The motion compensation unit determines spatial candidate motion vectors (MVPs) associated with a current portion of a video frame and prunes the spatial candidate motion vectors to remove duplicates without removing a temporal candidate motion vector. The motion compensation unit selects one of the temporal candidate motion vector or one of the spatial candidate motion vectors remaining after pruning as a selected candidate motion vector based on a motion vector predictor (MVP) index signaled in a bitstream and performs motion compensation based on the selected candidate motion vector.

摘要： In one example, this disclosure describes a method of decoding a frame of video data comprising a plurality of block-sized coding units including one or more largest coding units (LCUs) that include a hierarchically arranged plurality of relatively smaller coding units. In this example, the method includes determining a granularity at which the hierarchically arranged plurality of smaller coding units has been split when forming independently decodable portions of the frame. The method also includes identifying an LCU that has been split into a first section and a second section using the determined granularity. The method also includes decoding an independently decodable portion of the frame that includes the first section of the LCU without the second section of the LCU.

摘要： This disclosure describes techniques for calculating values of sub-integer pixels applied by an encoder and a decoder to encode blocks of video data. In one example, a video encoder is configured to receive values for a full integer pixel positions of a reference sample, apply an interpolation filter to a first set of the values for the full integer pixel positions to calculate a value for a first sub-integer pixel of one of the full integer pixel positions, apply the interpolation filter to a second, different set of the values for the full integer pixel positions to calculate a value for a second, different sub- integer pixel of the one of the full integer pixel positions, encode a current block of pixels using a motion vector that points to one of the first sub-integer pixel and the second sub-integer pixel.

摘要： This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, a plurality of feature points may be determined for a 2D view. The plurality of feature points may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. For example, the plurality of feature points may be used to generate a global motion frame difference. The global motion frame difference may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.

摘要： This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, an initial indication of depth (e.g., an optical flow) may be determined for a 2D view. The initial indication of depth may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. The initial indication of depth may be modified based on the estimation of global motion to create a global motion-adjusted indication of depth. The global motion-adjusted depth indication may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.

摘要： This disclosure describes techniques for performing entropy encoding and decoding of video coefficients using a joint context model shared between transform units having different sizes. For example, the joint context model may be shared between transform units having a first size of 32x32 and transform units having a second size of 16x16. Performing entropy coding using a joint context model shared between transform units having different sizes may reduce an amount of memory necessary to store contexts and probabilities, and reduce computational costs of maintaining context models. In one example, the joint context model may be shared between transform units having the first size with coefficients zeroed out to generate a retained coefficient block having the second size and transform units having the second size. In another example, the joint context model may be shared between transform units having the first size and transform units having the second size.
